This means Games for Windows Live players of Batman: Arkham Asylum will be able to earn Gamerscore points by unlocking achievements, and really that's about it. There's Live connectivity, but being a single player game, Arkham Asylum really doesn't get much of a boost from this.
Still, it is good to see more PC titles slipping under the Games for Window Live banner. Of all of the games released as part of the Games for Windows brand, only 15 so far have been Live-enabled. With DIRT 2, Battlestations Pacific, Fuel, Stromrise, and now Batman: Arkham Asylum all due out this year for Games for Windows Live, the service seems to slowly been picking up steam. Fingers crossed, Games for Windows Live!
