An anonymous reader writes from an article on TechCrunch: Microsoft just announced that game developers can now create cross-platform multiplayer modes that work with other consoles and operating systems. So it means that the next Call of Duty or FIFA could feature a multiplayer mode that works with both Xbox and Playstation gamers. It just depends on developers now. Microsoft has historically restricted cross-platform play as the Xbox Live was the first successful multiplayer network for consoles. And yet, Microsoft is now lagging behind the Playstation 4 with its Xbox One. By opening up cross-platform multiplayer, Microsoft could convince late adopters to buy an Xbox One even though their friends have a PlayStation 4. It's also a way to make sure that there are enough plays for less popular games. It's unclear how developers are supposed to deal with duplicated PlayStation Network and Xbox Live screen names.
