The thing with the OP's idea is that it limits you. Sure, it extends replay value, but I don't think that's how it works. In an RPG, a role playing game, I want to see a problem, and solve it however I see fit. I wouldn't enjoy being forced to play a certain way just because the game made me choose a path to follow.
Replay value doesn't necessarily matter if the game is already good. If it is, then you'll play it again anyway. Besides, its not like the developers/publishers care how long the game is; you're going to buy it anyway, no matter the length.
