It's too bad they couldn't have gotten a patch out for the game before they got a demo out. Just a heads up-the full game has MAJOR MAJOR problems. Just check out any CIV IV site. If you got ATI--get ready to jump through a few hoops to get it to run, memory leaks, lock ups requiring hard reboots, CTD (lots of crashes to desk tops). They briefly releases a patch then pulled it because of a bug. My game is just taking up H/D space until a patch comes out. The game plays fine, but when you get a crash every few turns in the later stages of the game, it's just not worth the effort.
