Amazing

User Rating: 9.3 | Sid Meier's Civilization IV PC
This game is really addictive. You will spend hours trying to beat it. If you really have no life, take on the terra map on huge at an epic pace (takes a couple days). My computer has crashed a couple times playing it, so be warned. The learning curve is really steep, if you've never played any civ games before, I recomend taking the tutorial at the begining of the game (voiced by the creator himself).

Pros:
religion is fun to tool around with
many technologies
a great range of difficulties

cons:
i wish there had been a larger concentration on seapower
not too many modes
pretty steep learning curve (especially if you're new to the game)
