I'm sorry, but I really really hate replaying games. Don't do it (discounting a couple classics like FFIX, which I have done a couple times during, oh, the last 13 years or whatever).
Forcing a player to replay the game over and over, including all those damn puzzles, is a fucking retarded and frustrating mechanic. Do I want to find out more about the story? Sure. Do I want to go through all the puzzles and all that stuff over again? Uh, no thanks.
If there was something that fast forwarded you to the decision forks in the game, then yeah, I'd give it a shot. But I don't have time to be playing through one game ad nauseum.
