With Quantic Dream's previous (and very weird) Indigo Prophecy available on multiple platforms, many gamers have been curious as to why Heavy Rain is a PS3 exclusive. PushSquare reports that Quantic Dream's David Cage -- once again -- explained the reasoning behind the game's exclusivity at the Eurogamer Expo. He first noted that any answer he gave would be "suspicious," but further explained that the PS3 hardware is "extremely powerful," adding, "If you make a real PS3 engine, then you can have really fantastic performances." He elaborated that porting to the Playstation 3 from other platforms "becomes difficult" (something we've heard before). Beyond technical reasons, Cage said that the team at Quantic Dream loves the console. "I play PSOne, PS2, it's really a part of my culture," said Cage. Cage also added that realistic graphics aren't necessary to create emotional characters, but noted that the goal of Heavy Rain was to create truly believable characters. "With this approach," said Cage, "PS3 was by far the best platform." Given what we've seen of Heavy Rain thus far, we'd be hard-pressed to argue. [Via VG247]
