Whats changed? Nothing.  I played the beta.  It is exactly like the first game with a location swap, and a couple comfort/convenience changes that SHOULD have been jn the first game.  So if you have the mental acuity of a 3 year old and played the first one to the point of retarded obsession..... you will like 2.  For everyone else who is smarter than a shoelace, pass on it.
