Uh...it's the steampunk.
Not that I don't care about the AI...the relationship between the Big Daddies and the Little Sisters looks amazing...as well as the general AI system. It's one of the reasons I'm getting the game. But the main reason is the content in the game, its setting, and the way the game looks basically. The way Little Sister's shadow worries you as she comes around the corner, only to be alarmed by the Big Daddy following her...that's what we love.
I don't know too many games that have this kind of atmosphere...other than something like Half Life 2...which is a must-buy for everyone anyway. If you're saying Halo has what this game has, then you're crazy.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
