Good thing there's a sequel coming up, right?
It's inevitable for all multiplayer games, but it's still a bummer to see. Phantasy Star Universe is closing its doors for the 360 version's multiplayer. Single-play will of course be still around, but Phantasy Star is and always has been a multiplayer focused game. Phantasy Star Online 2 is upcoming, but 360 fans are without, as it's only for the Vita and PC.
