If you wanted to follow the series, that's where you play them, on the Sony platform.
I mean, that's like complaining about not being able to play Gears of War because you have a Playstation(x). You're comparing two different scenerios. Those titles are on those platforms, but for the followers of the series, remakes should have been made on at least the successive platforms the original was made for. The original series, the first two titles, were on a platform that doesn't exist anymore and the NES. They moved on from those, so big whoop.
