When I bought Civ 4 I thought, "Why does a game have to be more complicated to be more fun?" Civ 4 is probably a fun game but I think it has gotten WAY more complicated than Civ 3. Civ 3 is simpler and more enjoyable because you can learn the game mechanics quickly and the way the game works is very straightforward. Civ 4 is different. There are SOOOOO many new icons, concepts, different style of play, resources, terrain, unit operations, that it becomes painful to learn entirely how the game works. Not to mention, the surpreme graphics of civ 4 slows my system down to the point it takes like 5 minutes for a unit to move 1 square.
