minecraft or roblox for 3d. Maybe gamemaker or smth similar for 2D.

Anything else & you'll fail, because you're only one on the "team" understanding how things work! :D (not that it's generally a bad thing to fail.. there's always takeaway from that as well)

You can then build a minecraft plugin for some gameplay specifics.

everyhing else (unity, unreal, coding from scratch) will fail you way sooner than you think. imo.
