I got this because I never played the original Fable and I'm having a great time so far. Yes, it is choppy and I've had my character slow down for no obvious reason and get stuck on things. The fights seem smooth so far, but it did freeze my 360 once. The load times are also bad.
This game has been given a fresh coat of paint but clearly has no been optimized for the 360. That's sad because it's a great game that deserves better. Come on Microsoft, this is your flagship RPG! Makes me less excited for the new Fable on the Xbox One and I love RPGs.
