Tier 3: Kung Fu Chaos
Rainbow Six 3 wasn't exclusive at all, and the PC version was far better. Crazy Taxi 3 was released on PC too, though I don't know how good it was.
I reckon that if you want to stick to your rules on "enduring quality" - ie. they should be the definitive games of the genre - you should take a much harder look at what you've got listed there. Are you seriously suggesting that Orta is the best on-rails shooter (even if you restrict them to dragon-based ones)? And that RSII is the best rally game ever? The others set themselves apart I guess - SB through gimickery, Otogi through having a distinct feel to it (even if that feel is "weird as fuck"), and I've not played Oddworld though it sounds unique enough, but the former two should be tier 3.
