There has been bragging about the AI. They've talked about the multiple tears of the AI. There hasn't been much news beyond that, because it not something a review can easily recognize as well done in a few hours of game play.-No bragging about the AI (they arent even trying to use it as a "new" feature-which means it will be stupid as always-unless modded by the community)
You can. That was misinformation. Apparently you couldn't in some demo though.-you cant even re-name cities
It's a big deal because it stops road spam, which was a major strangeness in previous versions of civ.-Road upkeep listed as a feature...desperate for features much?
City state are said to be a big influence on game play. Civs are goal oriented, city states use a bonus system similar to civ IV civs.-City state ideas seem actually interesting
(Note: positives seem like added fluff rather than big influences on gameplay/game quality)
