Re:Civilization game length (Score 1)

I'm not sure if this helps you, but we have already had it confirmed that there are 3 game modes-a short 200-turn game (which you can apparently finish in the space of a few hours), a Normal 400-turn game which will take a day or two at most, and an Epic Game, which can take anywhere up to a week. In addition, we know they are bringing back accelerated production, start in any era and the ability to tailor the total number of turns to as small or as large as you want. Therefore, it seems like the answer to your question is that a game can take as long as you personally want it to ;)!
