It has an aesthetic and atmosphere which synergize and augment its core gameplay, in which you make decisions eradicating millions of lives…Fun with friends but AIs play mathematically perfectly and there's no way to tweak them so solo play is very brutal and…Fun with friends but AIs play mathematically perfectly and there's no way to tweak them so solo play is very brutal and…its a good game but it lags frequently and crashes a lotWhy it fits
