Well Civ 4 the newest one with the best graphics (not counting Colonization), but I always loved Civ 3 the best. But I would highly recommend Civ 4.
Edit: Civilization isthe best turn-based strategygameseries around, and one of the best strategy series ever made. I don't think any other developers have matched Firaxis's ability to make a great strategy game.
I think Civ 2 is the best of them all, especially with the live action advisors. Hilarious.
Although, my friend and I thoroughly enjoyed Civ: Call To Power..we just called it Civ 3 though. I would say, however, that CTP is the one where the devs went out on a limb and took many liberties with the units, wonders, and buildings you could build/create. Warmechs, starladder, sea and space colonies, etc. It was a bit over the top, but still very much enjoyable.
wow! all these differing opinions. I guess I will have to just try them for myself. how about polulous or age of empires do they compare to civ?cezalinho
Never played Populous (I know, I know) but Age of Empires is a real time strategy. Basically, you have to worry a lot more about resources and getting an army built up fast in a real time strategy game. Its a completely different style, but if you like civilization youll probably like real time strategy games as well.
