Has Rom said its different or are people just assuming it is?
Surely they wouldn't make such drastic changes from one build to another in that short space of time
Its hard to put a finger on it. Rom seems to think they have reigned back some of the passing error and stuff, to me it looks like a better textured version of the build we played in Canada with missing animations put in.
I am guessing its a combination of Beta refinement and tweaks that have made the game appear to play slightly differently.
