Many people have knocked the Source engine graphics without actually looking at it...especially the final version. Play the demo on high settings (which shouldn't be hard for an average PC gamer) and I think it'll hold its own against any other current game.

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 )
