Summary: I returned to Civ IV after trying Civ V because of the vastly superior game play in the earlier version. Version V loses much of the functionality of the earlier versions and dramatically slows system speed.
Summary: This is one of my favorite games of all time and I still keep coming back to it after years. Great game design, diplomacy, and scenarios. The random events of the expansion are a bit annoying but add a dimension to the game that was not there before.
Summary: The version I bought came with Civ III and all of its expansions, Civ IV and all of its expansions, plus Colonization. People looking at this game probably already know about the same, so I just wanted to point out that this is a great value, even if it doesn't come with Civ III anymore.
Summary: I used to play Civ 4 but had switched to Civ 5. After playing Civ 5 for over a year, I actually prefer Civ 4. The AI could use a little work, but I think the game-play is better. Civ 5 seemed to focus more on the graphics and seemed to dumb down the gameplay. The time Civ 5 spends processing turns is ridiculous and when you got near 400 turns the game would just crash.
Summary: I don't have much PC games, but this one tops all my PC games. Writing this review right now makes me want to play it. The game sucked me in and I could not believe how addictive it is. You research technologies, build cities and buildings, explore, and the best part: declare war and fight! Each map is different, and you can choose what map type you want, you can also choose the climate, difficulty, and your civilization.
