I remember hanging out with a friend back in the day and watching him playthrough this whole game on the Xbox 360 in one day. He got to the very end and then his power went out and since this was before auto-saves were implemented in every single game and he hadn't saved the game a single time, he had to restart from scratch. Don't think he ever beat the game after that lmao.

Moral of the story is remember to save in games you play periodically, especially if it's an old game.
