Developer Rocksteady has confirmed that the PC version of Batman: Arkham City will be using Microsoft’s Games for Windows Live platform, rather than Steamworks as had been rumored. Some buyers are bummed about the decision to go this route, but apparently it was not that unexpected according to some we spoke with.

While the decision to go with GFWL will not stop the game from being sold on Steam, it seems now that many players are looking for PC developers to fully embrace Steamworks. The biggest announcement so far was the news that Call of Duty: Modern Warfare 3 for the PC would use Steamworks.

The PC version the game will be sold at retail as well as a number of other digital distribution methods for the PC, including Steam.
