Really surprised that game never went multi platform at some stage, it would have done just as well on PS3 / PC.

Dead Rising is still the weirdest franchise I have ever seen handled. It's been exclusive, not exclusive. Some titles here and not there. If they could get DR1 and the Cases for 2 on PC we could finally have it all in one place.
Good point, we are so close to having everything available on one platform.
