I'd say the game is somewhat frontloaded, which I suppose has something to do with the sameness of environments and enemies. You get this "big" world to explore, except the actual explorable areas are strikingly similar from the last. Bower Lake being one of the prettiest areas in the game might be responsible, too. Not a bad game, but I don't think they really remedied many of the important shortcomings of the first game.
I agree with that. Fable II is a fun game to play for a while, but it never really overcomes the problems that plagued the first game.
-Worlds are MORE open, but still not THAT open.
-Interaction is more diverse, but still simplistic and very easy to master either way.
-Companion are still fairly useless.
-Marriage can produce offspring, but there's not much you can do with them.
-It's STILL not really allowing you to live the entire life of your hero. It's all in steps that stop short of old age and death.
Aside from its focus on a few key areas, it still not really that much different from any other action-RPG out there.
