For this current game, I unchecked the 'science victory' condition. The only other thing I did different was that in the previous sessions, I experimented with different game speeds for the first time. Now, playing on the Prince difficulty level as Kongo, standard speed, with small map size, on Pangea, I notice after 160 turns that none of the civs are building campuses, apart from a couple of city-states. There are no theatre square districts either. Just encampments, wonders, holy sites. It has kind of ruined the game. There's no point in continuing when I have 3 times as much science and culture as those chumps. Any idea what went wrong here? Is there a file or a setting I can check?
