This was somewhat lost in the shuffle of Wednesday's announcement that Skullgirls, the 2D fighter currently available on PlayStation Network and Xbox Live, would be getting a PC version. The game's official Twitter feed says that PC and PS3 gamers will be able to play together thanks to cross-platform compatibility, but it won't be implemented "until a few months" after the PC version releases.
This was in response to a question as to whether Skullgirls would use Games For Windows Live. If it's cross-platforming with the PS3, then "definitely not GFWL," the game's makers said. So that is a double dose of good news for fans of the fighter.
