Does anyone know why the game just ends sometimes? It happens for victory sometimes and other times for defeat. I don't have any warnings and I'm not going to satisfy any victory conditions in blank number of turns. Is there a time/turn limit on certain games? Usually happens when I'm trying to research most of the tech tree and I've already "won" the game. I've made certain that I won't achieve an influence victory by limiting my influence. Thanks.
