The move to 3D doesn't come without a cost. It was easier to make really huge maps in 2D. The largest maps in Civ 4 will be a bit smaller than their Civ 3 counterparts but there is a lot more going on with all the animations and all the available information. One thing we will be introducing to help is the idea of game speeds. Players will be able to play a normal game, of course, and this will have a pacing similar to previous games. They will also be able to choose quick or epic game speeds in which the game will be scaled to be either quicker or much longer than a standard game
