I seem to recall that MS saved the game basically. Remedy ran out of money during the long development. Since MS obtained all rights for the game, they used it as one of their Xbox-kills-PC split personality schemes. It was initially going to be Vista + 360 but then went 360 exclusive.
It's cool to see it selling on Steam. I wonder if that drops off quick or not....
