A funny thing happened on the way to the upcoming multiplatform Dead Rising 2: Capcom managed to alienate its Sony PlayStation 3 and PC-owning audiences.  Not only is the game's prologue, Case Zero, exclusive to the Microsoft Xbox 360, but now GamePro has the news that there's a 360-exclusive epilogue as well (entitled Case West).  Recall that the original Dead Rising remains exclusive to the Xbox 360, too.  That's a large chunk of Dead Rising content that those without Xbox 360s who may be otherwise interested will not be able to enjoy.  I'm starting to wonder why, as a PS3 owner, I should bother to get involved with this franchise knowing that I cannot experience the complete storyline.  I feel as though I'm being asked to read a book that is missing the first and last few chapters, and although the middle of a story can be very satisfying, I need the setup and conclusion to really appreciate the complete narrative.  Now, console-exclusive content is nothing new, but typically it's a spare playable character or extra weapon that is held back from one portion of the audience.  When entire sections of storyline go behind the wall, that's going too far.
