Addicting game! Not as detailed as the third one but still is a game worth picking up.

User Rating: 9.4 | Sid Meier's Civilization IV PC
This game was 2k's first cilvilization game, I think they did a good job overall. If you played cilization 3 you will notice that the fourth it is not as detailed as the 3rd but the update graphics and a few new features Cilization IV is a great game for against AI or PvP. If your graphics card is a newer one then the world in this game will look stuning. You can download maps, and scenarios of certain websites in case you get bored of some their many game features. The only bad thing about this game is that cavemen cannot destroy tanks anymore ;) ,ok if you never played the last cililization game then you wouldn't get that joke hehe.
