Let's name TRUE exclusive franchises by letter.

So we're using the Wikipedia definition? I disagree with it, but I can accept it.

Why are we using "exclusive" to mean "has never had any games on any other platform ever"? I submit that a better definition is "currently only offered on one company's platform(s)". This would make the list far more relevant and would allow for people to contribute to the list without having to worry about some esoteric offshoot or port.

Well I always considered Mario etc. as franchises and stuff like Mario Kart, Mario Bros. and 3D mario as series. This list to put it simply is a "you can't play this franchise anywhere else" list.

I would consider Mario to be more of an IP, but I guess that's just semantics.

My point about exclusivity is that while you may have been able to play, say, Halo: CE  and Halo 2 on PC and Mac, all subsequent Halo games have been exclusively on Xbox systems. Any list that doesn't consider Mario to be a Nintendo exclusive and Halo to be an Xbox exclusive is ridiculous.
