Just got it as well. Messed around in CAW, Create a Story, Create an Entrance Movie, and played the beginning of the CAW RTWM. Caw has improved load times that are very noticeable. I did notice that if you place certain things on top of one another, the lower layer will clip through the top layer, appearing like a game glitch. Not sure if this fixes itself once the wrestler is fully rendered.
The Road to Wrestlemania storyline for the CAW has been fun so far.
I'll be playing some more later today. One thing I hate is that the code to unlock Stone Cold requires XBOX live, which I don't have
