I don't have much to contribute, but the name "Rephsis" seems borderline unpronounceable to me (maybe that's why the empire is crumbling? :P). I don't know whether you had some inspiration behind it, but to me it has a strong "I combined letters until I had a word that looked new" vibe.

The screenshots in the Steam page do look impressive though! As an outsider, I could mistake this for a recent Civ game. Congrats on making it here!

I would assume it's pronounced like ref-sys, which seems not too bad to me.
