Nintendo has almost ALWAYS put the "Only for Nintendo" label on their exclusive games. Super Metroid was actually the first game they did that with, and they have continued doing it to this day. Microsoft saw it as a good marketing tool and ripped Nintendo off.

And I have to agree with Rabber on this one. I own a grand total of 2 PS2 games, in comparison with 8 GCN games. Nintendo just makes better product. The ONLY thing Sony has going for it is a number of 2nd party licenses. Square, Eidos and a few other companies like Rock Star are the only thing keeping PS2 on the market. Without those few licences (of which the TWO biggest are no longer exclusive to Sony) Playstation has no future.
