Even though I just got Kingdoms, I must say the Americas is definitely NOT the least bugged - I can't even PLAY it! It crashes every time I go to fight a battle. I get into the battle screen, and there are no textures anywhere - just men floating in midair - and then it crashes. Sigh. Updated video drivers and all, so this kind of annoys me.

The Crusades campaign is the only other one I have played, and encountered no bugs at all but I didn't play it for more than a few minutes.

On a closing note - does anyone know what's wrong with my Americas campaign? Might help save some forum space by asking here instead of making a new thread.
