Man, I don't trust the cartoons though. I assume you're talking about the Mario Brother's Super Show and all those, because I'm not aware of any other show. Anyway, my point is that the cartoons contradict the entire series, not just one game (Yoshi's Island). So I don't consider them as having actually happened at all. And as for the comics, I suppose you have a point, and once again I'm going to make an assumption that you're mostly refering to the small strips that used to appear in Nintendo Power. However I don't think any of those comic strips should be acknowledged. For example, fans of the Metroid series (such as myself ^_^) don't see the events in those strips having ever happened, otherwise we'd have to except the fact that Houston Armstrong was an actual character *shudder*.
But I'm getting waaaay off track. My point was that since SMW2 came after the comics, and since it's an actual game as opposed a short little comic strip, then it should override the comics. Kind of like how the Mario Advance series overrides the older games. Or at least that's the impression that I've gotten from most of the fans.
Anyway, if I've missed something or just misunderstood, please except my apologise.

Pessimists are technically happier people. They think things will suck...and if things do suck they just say ''Oh, I guess I was right''. Then if things don''t suck they get a sudden surprise...unexpected joy. So the worst thing that can happen is you''re proven right. An optimist can be let down but a pessimist can''t
