“Mac will try hard not to let you run this; it will tell you the app is damaged and can’t be opened and helpfully offer to trash it for you. From a terminal you can xattr -cr /path/to/OpenCiv3.app to enable running it.”

How far OSX has come since the days of the “cancel or allow” parody advert.

The lockdown has been slow and steady. Slow enough that at every juncture, apologists point out that it is still possible to run software you choose. I think we enjoy freedom that people do not appreciate because they never had to earn it. Gaining it back will require extraordinary effort.

WildWeazel|23 days ago

Mac support is the bane of my existence. It doesn't help that none of us core contributors have one, so if anyone is willing to be a lab monkey...

tclancy|23 days ago

What is going on with this? I tried that and the alias I have built in for this problem, `make_safe() { xattr -d -r com.apple.quarantine $1 }`

The application cannot be opened for an unexpected reason, error=Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0xae1038720 {Error Domain=NSPOSIXErrorDomain Code=163 "Unknown error: 163" UserInfo={NSLocalizedDescription=Launchd job spawn failed}}}

I got a Mac only because of the excellent battery life. But I dread Os X. Not only it is dumbed down and it is harder to accomplish what is trivial in other operating system, but I have to actively fight against it if I want to run software that is not downloaded from the app store or I want to open files with apps I downloaded from elsewhere. And the UI is broken.

ceejayoz|23 days ago

To be fair, the threat landscape changed, too.

heavyset_go|23 days ago

This is the reason I dropped macOS as a platform target. Apple will make users think you're a hacker trying to trick them, because macOS acts as if your app is radioactive if you don't pay the Apple tax, and refuses to let users run the apps they want.

Maybe 1 out of 1,000 users will know the magic ritual required to run what they want on their machine, and for every one of those, 10,000 are gaslit into thinking you were trying to harm them by macOS' scary warnings and refusal to do what they want.

jmspring|22 days ago

It gets a bit old and sad when this topic and macOS processes dominate the comments section.

Like windows complainers, most of us do not care.

neocron|22 days ago

And yet people still support it by finding ways around it instead if just leaving mac in the dust, simply not supporting it. Worked for Internet Explorer, will work the same dor mac

miki123211|23 days ago

"cancel or allow" (which Microsoft still does) makes no sense, it just trains user to click "allow" every time. Users don't know what they should allow or not.

It makes a bit more sense on accounts that have a password set, as it requires you to confirm identity when introducing significant changes to the system (and this is something that Apple also does).

Gatekeeper is a different thing, it basically makes sure that the software you're trying to run has been pre-scanned for malware by a trusted party, similar to Windows's "smart screen" and Defender or APt's GPG keyring integration. It's a mechanism that is completely invisible to 99+% of users. If you see a Gatekeeper pop-up and the app in question is not mlaware, the developer is doing something very wrong.

Civ III is still my go-to activity for long flights with no internet - I've yet to find a better way to instantly time-travel forward 12 hours.

I haven't tried OpenCiv3, but I'm glad it exists - getting vanilla Civ III running on MacOS is a hassle and still has issues with e.g. audio and cutscenes. I also hope it leads to a way to improve worker automation. Managing your workers well is important, doing it manually is tedious, and the built-in Automate feature is really bad.

b3ing|23 days ago

I like Civilization games but they make 4hrs feel like 30min, so I can’t play them. Otherwise it would be the year 2060 already

jwilliams|23 days ago

It used to be Factorio for me (I live in Australia, so long flights happen a lot). The problem with Factorio the flight isn't long enough! and the game bleeds into 100+ hours post-flight.

SilverElfin|23 days ago

> I've yet to find a better way to instantly time-travel forward 12 hours

I find it very hard to use a computer in the cramped tables of the plane. And the person in front always ends up aggressively reclining only when I have a laptop out. Plus I feel bad that maybe my bright light is disturbing the people sleeping next to me.

colechristensen|23 days ago

The key here is seeing this mentioned and not time traveling forward until 6 AM Saturday morning.

kilroy123|23 days ago

How did I not ever think to do this? Such a good idea.

felixthehat|23 days ago

Yeah civ VI on my iPad with an apple pencil kills flights

ddp26|23 days ago

How do you manage the laptop + mouse?

Der_Einzige|23 days ago

The total war games are like civilization but with actually good combat. Especially if you get mods like DEI for Rome 2, RTR for Rome 1 remastered, etc. It's regrettable that we let the grimdark warhammer crowd define the series.

The paradox grand strategy games are like civilization but with real agency and at times straight up historical accuracy.

Meanwhile I have to deal with Ghandi actually nuking everyone (the bug is ACTUALLY REAL IN CIV 5, the best modern civ game!). Not sure why Indians aren't mad as hell at the whole series.

WildWeazel|23 days ago

Hi all, OpenCiv3 founder here. Thanks for the support! Check us out on Civfanatics or Discord to keep up with the project.

slazaro|23 days ago

Any interesting insights about using Godot with C#? I love C# and I'm happy using it in Godot even though it's not as seamless as in Unity: in Godot 4 we still can't export to Web if the project is C#, and there's the whole conversion between C# types and Godot types that adds inefficiencies and extra allocations, etc.; it feels like it's a second-class language in Godot.

I'm always interested in seeing what people find when developing larger projects in C#.

davely|23 days ago

Oh my, this brings me back! One of my fondest gaming memories involves a massive Civilization 3 PBEM match between a number of Civilization fan sites, where we all had private forums and ran these virtual nations against each other. This was way back in 2002 or 2003!

I believe Civfanatics was in it (run by “Chieftess” if I recall), Apolyton (which I was a member of — elected in as Minister of Public Works and had to come up with a plan to clear our pesky jungles) and a number of other sites.

It was such an awesome time. Real diplomacy and trade negotiations between the fan sites while waiting to play our turns. Man, it was fun.

ukuina|23 days ago

Would it be feasible to add an API to OpenCiv3 (or run it as an SDK) so we can script up actions?

genocidicbunny|22 days ago

Good to see you around here! I remember some of your posts way back in the day. I don't recall, did you hang around the civfanatics IRC much back in the day?

jcurbo|22 days ago

This is great stuff! Civ3 is still by far my favorite Civ. And a nice use of Godot.

klaussilveira|22 days ago

Thank you for creating such a badass project.

popalchemist|23 days ago

Have you considered adding LLM features for the negotiations? Could be cool.

bigstrat2003|23 days ago

I love that the community is doing this, though I'm curious why Civ 3 in particular. My understanding was that "classic" (for lack of a better term) Civ fans tend to prefer either 2 or 4, and that 3 was considered to be not as good. But perhaps I was mistaken as to the community's opinions on the games.

caminanteblanco|23 days ago

I can definitely vouch for the 2 or 4 narrative, those have always been my favorites of the 'Modernish' civ games, but my favorite will always be CivNet (Civ 1 with multiplayer). There is some real simplicity in Civ 1 that makes it much better suited to a multiplayer experience than the later entries. It is a real pain to get any non-hotseat multiplayer working nowawdays, but well-worth it.

acessoproibido|23 days ago

For me the most classic one is Civ III by a mile. 4 was way too modern/ flashy for me and 2 too old school. But maybe I was just born at the right time for 3.

thrance|23 days ago

There's Freeciv [1] for IV, and Unciv [2] for V. I doesn't have many fans, VI is too recent, and VII, well... Let's not talk about VII.

> Civ fans tend to prefer [...]

I'd say, each entry in the series gets love. The saying goes: "Your favorite Civ game is the first one you ever played". In my experience, that's pretty true (Still stuck on V).

[2] https://github.com/yairm210/Unciv

WildWeazel|23 days ago

Because it was born out of the Civ3 modding community which has been wanting a remake for 20+ years.

Sounds like you've been listening to Civ4 fans. ;) 3 is just as active on steam and has a very active and loyal multiplayer league.

toast0|23 days ago

FreeCiv covers civ 1 and 2 more or less.

Personally, I didn't play much of 2 or 3, so I don't have strong feelings either way.

packetlost|23 days ago

3 is my favorite in the series, but maybe that's not a popular take.

warmwaffles|23 days ago

I actually preferred Civ 3 to 2 and 4. It scratched a certain itch.

daotoad|23 days ago

Anecdata:

I'm a Civ3 hater, give me 2 or 4 any day. 3 is my least favorite version of the game.

But, OTOH, my wife is ride or die for Civ3.

afavour|23 days ago

> with capabilities inspired by the best of the 4X genre and lessons learned from modding Civ3. Our vision is to make Civ3 as it could have been

Looks to not be a straight remake. I wonder whether 3 is a preferable target because things like graphical complexity in >= 4 is too much.

TheRealPomax|23 days ago

Civ 1 and 2 have already been done, so if you want to play those, hit up freeciv.

TheGRS|23 days ago

Can I tangent on your question here and ask what others think of Civ 7 now? When I learned about it I thought it was a day 1 game purchase for me for sure, but I held off when I saw a stream of bad reviews. I figured I'd come back when they ironed the problems out (as they've done in every major Civ release to my memory). Haven't taken the plunge yet.

danielparsons|23 days ago

civ 5 is now the most popular among hardcore civ fans. still in the top 100 games on steam. more than 2x the player count of its sequel

cyphar|23 days ago

I must admit that there is a certain sense of nostalgia I get from playing Civ 3 that I never got from any of the other Civ games, but that's probably just because it was the first Civ game I played and got really hooked on as a young kid.

GaryBluto|23 days ago

I very much enjoy Civ 2 and 3 and would've played 3 more, but the 3d rendered sprites make it much more of a pain to add anything graphical to.

sevenseacat|23 days ago

that was my first thought, I was gonna show my husband this but he's a Civ 2 ride or die

JumpCrisscross|23 days ago

Is 3 the one with forced retirement?

caminanteblanco|23 days ago

For those like myself who have wanted this but for Civ1 (all 4 of us), someone on CivFanatics has made incredible progress, and the game is actually playable now: https://github.com/rajko-horvat/OpenCiv1

culi|23 days ago

So there's

- OpenCiv1

- FreeCiv (civ 2)

- OpenCiv3

- ???

- UnCiv

I'm curious why civ 4 is the one that got skipped. I feel like it's the one that is most commonly labelled as the "peak"

yobert|23 days ago

I'm with you-- civ 1 is by far the best! I adore the wonky graphics. None of the new ones hit the same.

rl3|23 days ago

It's really cool to see projects like this designed for dropping in assets from the proprietary version. The separation in the first place is unfortunate, but at least the capability exists.

Civ III in my opinion had some of the best art of the entire series. The 3D feeling of the successor games are kind of off-putting by comparison.

0cf8612b2e1e|23 days ago

Isn’t that pretty common for the open source remakes? Let the programmers focus on the coding and outsource the art.

glimshe|23 days ago

I once had 10 civil war-tech troops with rifles lined up against a fort with ONE bow and arrow troop. I lost every single one of my troops and that's the last time I've played Civ 3 in my life. Hopefully they addressed this issue...

(PS: once a friend lost a battleship to a stone age militia in the original Civ)

supertrope|23 days ago

Civ III battles are best thought of as dice rolls like the board game Risk. If you have more modern units you get to roll more dice but there's still a small chance archers defeat musketmen.

daotoad|23 days ago

I lost a nuke to a phalanx in Civ 1. Still salty about that _decades_ later.

nasretdinov|23 days ago

Civ V definitely solved the issue by separating unit strength and their HP. Not sure about Civ 4, but I think it applies there too.

WildWeazel|23 days ago

tbh that's a civ rite of passage

jmyeet|23 days ago

I have a long history with the Civ series. I spent a massive amount of time playing Civ1. My next most played was Civ4 and most of that wasn't the base game. It was a mod that had a very loyal fan base: Fall From Heaven 2 [1]. I have tried a couple of times to get all this to work on a modern PC but I think I'm played out on the game and I never quite get it off the gorund. I have a ton of nostalgia for it though.

Civ5 started the whole hex thing, which I was never excited about. Yes, Civ4 had stacks of doom but Civ5 turned into a puzzle of moving units in order because you could only have one per hex.

Anyway, Civ2 and Civ3 never got as much play from me. I'm a little surprised that people had the same enthusiasm. My memory of these 2 was that they just added a bunch of tedium, like I distinctly remember that tile improvement changed to turning farms into supermarkets. It's been a lot of years so I might be misremembering. Maybe I just dind't give them enough time. Or maybe nothing could capture my initial enthusiasm for the novelty that was Civ1.

Anyway, i'm always happy to see projects like this. Games really do live forever. Like people will invent software for free to keep running them (ie emulators).

The Civ series has kinda defied the usual trend to entshittification. I'm really thinking of SimCity here. It's hard to describe how much EA shit the bed with SimCity %, so much so that it basically launched Cities: Skylines, which itself has had issues with the CS2 launch.

Does Civ3 have a massive fanbase compared to Civ1, Civ2 or Civ4? I really don't know.

danielparsons|23 days ago

I love the hex system - adds a lot of tactical depth. Choice of naval vs air vs land focus often comes down to who you're fighting and where. Then you turn around to fight someone else and realize your 20 veteran frigates are near useless despite your new enemy being coastal because all of their cities are tucked away in bays or behind hills...

miki123211|23 days ago

This feels like the perfect game to add (screen reader) accessibility to.

Sadly, I don't think it can be done by us screen reader users, as the Godot editor UI is not really accessible (though they're apparently changing that in the latest version).

isomorphic-|23 days ago

I encourage people to try Unciv. It is the best open-source Civ clone for desktop/mobile.

https://github.com/yairm210/Unciv

miclill|22 days ago

Cool. It seems Unciv is basically Civ V while openciv3 is Civ III, if anyone else is wondering...

shevy-java|22 days ago

Strangely enough I still think Civilization I is best.

Later versions added better graphics, some interesting gameplay choice and elements. But all of them felt much slower gameplay wise compared to Civilization I.

I feel in a similar way with SimCity. I liked the follow-ups and they were a bit better in terms of gameplay compared to later Civilizations, but the first version is still by far the best, even if young people today will find the graphics crap.

There is something about purity, to get the most basic parts out. Games today are more like movies. They may be fun but they feel more like playing a movie than a game. Little Nightmares was interesting, pretty to look at and fun from a game play perspective too, but ultimately I feel that the modern games lost something fundamental that they may never get back (at the least non-indie games; indie games are a bit more varied).

bigcat12345678|23 days ago

Yes CIV3 still feels to me the peak Civ experience.

The content is a bit lacking though, would see more diversity in tech tree, and units.

jlarocco|23 days ago

I don't know about the dedicated Civilization fans, but 3 was the only version I played.

I didn't play it much, but when I did I'd play for 6+ hours at a time. I'll check this out later tonight, and might see if I can find the old CD and get the original running.

sevensor|23 days ago

Ooof, good luck. Civ3 copy protection was intense. I had to get out my old Win2k disk and stand up a VM. Attempts to rip an iso will be complicated by the fact that they deliberately wrote bad data to the disk. All of this is surmountable, but unless you enjoy a very particular kind of fun, you may prefer to spend $2 on GoG.

syngrog66|23 days ago

UnCiv is the best FOSS clone of Civ I've played

einpoklum|22 days ago

I'm old enough to have played Civ I when I was a child, but have not played since then. So, why didn't this project choose to create a Civ 7 or Civ 6 play-alike, nor a Civ 1 play-alike, but rather Civ 3? What's special about it?

More generally - if someone remind us of the major differences between the different versions of Civilization, in a nutshell, we would be in your debt.

mfld|23 days ago

This looks great! Shout out to FreeCol, a reimagined Colonization, that has the same isometric look and is a lot of fun.

PlatoIsADisease|23 days ago

Wake me up when OpenCiv4, but only when there's an option for smart AI rather than boosted fake AI.

I remember losing 6pm to 3am playing civ 4 one time. One more turn...

(But I'm not sure what I need openCiv for... the steam game is good. Maybe its just useful for the long term.)

1980phipsi|23 days ago

I would love to see someone use modern machine learning techniques to make a kick ass Civ AI.

JojoFatsani|23 days ago

Civ4 is super cheap on Steam BTW

ubixar|22 days ago

been following OpenCiv3 with interest. curious if you've been using any AI coding assistants to speed things up, or if it's been mostly vanilla dev? the codebase looks pretty clean

tbmtbmtbmtbmtbm|23 days ago

looks super cool. I'm a lifelong civ player but my first one was civ 4, so this seems like a fun chance to dip into some of the earlier ones. love that they're using Godot for the engine!

dnautics|22 days ago

I'm one of the weird ones that really wants an open source Civ:CTP. Especially if you can still edit the .ini file to have 255 civilizations on the map.

reconnecting|23 days ago

Interesting choice of version.

I just realised that the actual latest version of Die Ha… Civilization is VII (2025), and for me II remains the gold classic.

Both in Civilisation and in Die Hard.

SPascareli13|23 days ago

Freeciv was what brought me too the civ world, I'm sure this project will be the same for many children of this generation.

marcd35|22 days ago

ive never played before. i moved my guys around the map for 6 turns then they just disappeared. also cant figure out how to increase the scaling of the screen

mcfedr|23 days ago

wow, look at me stuck in the world of freeciv (civ 2)

JumpCrisscross|23 days ago

Any chance the AIs will be easily extensible?

WildWeazel|23 days ago

Hopefully yes, because so far none of us are AI programmers...

but seriously yes everything about the game will be designed for customization

rkagerer|23 days ago

Neat! Civ 3 was always my favorite version.

p0w3n3d|22 days ago

jrm4|23 days ago

uh oh

yeah, that's dangerous for me, this is the ONE that got me started
