Halo Reach won me over before it was announced, because I was nerdy/bored enough to have actually read the novel 'The Fall of Reach'. And while the game doesn't follow the events of the book, the story was so badass I was just waiting for them to make a game about Reach. If they really scale up the campaign to be as epic as they say it's going to be, it's probably going to be the best Halo game yet.
