I think there was someone that talked about CIV games.
So on EPIC there is free Sid Meier’s Civilization VI: Platinum Edition

Civ 1
Kike challenge
0% science rate after tech required for diplomats is discovered
Only allowed to build diplomats as a unit
You can build city improvements
You can use other military units or settlers you captured but you can not directly build military units or settlers on your own
You can get whatever you are given as a gift by having a unit step on a hut
