The demise of Marvel Universe Online leaves Sony Online Entertainment's even more mystery-shrouded DC Comics PC and PlayStation 3 project as the highest-profile officially sanctioned comic-book massively multiplayer game in development. (City of Heroes and City of Villains, which feature character-created superhero characters, remain online.) It also comes shortly after Marvel ended its agreement with Electronic Arts to codevelop a fighting game. The company still has longstanding agreements with Activision and Sega to develop non-MMOG games based on its iconic characters.
