Civ 4 restored my love for the Civ series!!!! The upcoming expansion pack will also keep the game on my hard drive.
User Rating: 8.9 | Sid Meier's Civilization IV PC
I hated Civ III with a passion, probably because I am a casual Civ gamer who never has delved too deeply in the different strategies of the game. However, Civ IV made some key adjustments that to me made the game more accessible (esp. the UI and city screens) and eliminated much of the frustration of playing (we now have real borders and can have a closed border policy). So while I'm no better at playing the game I am having more fun because I can follow the action easier and learn more quickly from my mistakes. I think the upcoming expansion pack will force me to keep this game on my hard drive forever. If there is a Civ V I don't think they can do it much better than this one!
