I played and beat fable and while I enjoyed myself I feel the game didn't live up to the hype. the character ages really fast (if you don't know what i mean, remove his helmet towards the end of the game and his hair should be completely white but that may have something to do with the path you choose) and isn't nearly as customizable as I expected, appearance wise anyway. I liked the ability customizing system although i feel the strength and skill could have had some more in depth abilities. I found it shorter than I expected and was also dissapointed you cant compete in the arena more than once. But it was still a pretty good game.
I noticed the aging as well. It is funny how it keeps track of th time spent on it. It would say some thing like 10 hours plays . Then days in game gone by 4 but your chatacter would have aged 40 years.
