Firaxis has released another Challenge Of The Month for Civ6: One More Turn! To be honest, that is each day a challenge for us, but we forgive them this ;).
In this challenge Age-of-Steam Victoria on a small continents map on quick speed on either Prince or Emperor difficulty. Your main challenge though is to achive Diplomacy, Culture, Science, and Domination victories in a single game, not limited by any turn limit. Interested? Check out the thread here and come discuss with us.
