Just what the title says. I used to be able to play a game of Civ 4 on normal speed in 2-3 days, usually taking between 10-15 hours per game. Now with Civ 5, I've been playing the same game on normal speed since Wednesday when I bought the game and I'm only on turn 300. According to Steam, I've played Civ 5 for 23 hours so far, all on the same game.. Maybe its just me, but Civ 5 seems like a REALLY long game. Thoughts?
