PyCiv

In 2020 during lockdown, I learnt Pygame by making this, which hopefully excuses any issues. Updates and fixes are unlikely because I don't enjoy trawling through misbegotten, year-old code. 

In PyCiv, you run a civilisation, starting with a sparse, nomadic population and advancing into an era of great architecture and wisdom, until you inevitably perish.

Features a technology tree, random disasters, four wonders, and probably other things I don't remember.
