The word on the street is the PlayStation 3 will feature one login for all games, even those that don't use the Sony buddy list and messaging system.
Dan Brooke, producer on launch title Resistance, told GamesIndustry.biz that he "wishes to be clear that Resistance uses the PlayStation online ID to sign into the game. There is no separate login for Resistance and the online ID you create will be the same you use for all titles."
Sony confirmed the news, too. So it's true. So there.
