Afterall how do you define exclusive?

[Torillian]

An exclusive to me is something only available on a single gaming platform. This includes iPhone, and PC, but it's imperative that the experience of the game be largely the same. I would not discount Spore as a PC exclusive because the DS version is so markedly different in it's experience, because if I remember correctly it takes out many features of the game, not just graphics. But I would discount games such as the new Platformer said to be coming to PSN, since it is available with almost exactly the same features on PC
