You can play it on your own pace in singleplayer, because itÂ’s turn based. You can either really think things over, or you can make your moves rapidly. Depending on this and your strategy and your playing style, a game can take anything between three and five hours. I think the beauty of Civilization is that, if you played it once, that only means that you want to play it again. ThereÂ’s 16 different civilizations to play. Even to play them each once would take at least 50 hours. Then, thereÂ’s difficulty levels, every map is different when you start a game. So thereÂ’s plenty of play time involved. But you can finish a game in just one evening.
