see also: Unciv, a Civ V reimplimentation. It's available for Linux, Mac, Windows and Android.

I hope there’s an iOS port sometime

So cool.... Hope for an android port since they use Godot.

Huh, will be interested to try this and see what changes they implemented to 'modernize' it. I used to mod the hell out of Civ3 back in the day, but I also remember the base game being pretty solid.

The art assets need to be imported from the proprietary game? Is there a screenshot of the game with its own "primitive" assets?
