Sony just put up a new Starhawk post on the Playstation Blog that talks about the ways of playing Starhawk with other people. The game had a split-screen option that lets each player log into his or her Playstation account:

Dual Log-In: Yes, two players can sign into on one PS3. You can sign in using your PSN ID on the same machine and retain the XP you earn at your friend�s house. And you can still take that hard-earned XP home with you and apply it to your character there. Although, if you�re Player Two, you can�t earn Trophies or character customizations (outfits, paint jobs, decals) as these are saved directly to the PS3. It�s not perfect, but it�s way better than Warhawk where Player Two couldn�t level up at all. You can play Co-op off-line as well, but no stats get recorded.

This is the first time I’ve heard of a game letting players log into two accounts on one console, but then I don’t follow multiplayer that much. So my title isn’t rhetorical: does anyone know if this is a first?

Also kind of refreshing to read “It’s not perfect…” in a post like this. Honesty…what a refreshing concept!
