Unlocking characters should be an excuse to try other modes of play, and challenge yourself in ways you normally wouldn't. (I may have liked SSE, but I didn't like unlocking everyone through it...)
In other words, the process used to unlock a character should reveal a new way to play the game... further expanding on just what the game can really be and encouraging players to experiment just to find them.

Well, you had Falco, which requires you to beat 100-Man Melee/Brawl. And then you got Wolf, who requires yo to beat Boss Battles. (Funny how both are Star Fox characters)

But yeah, I can't think of much else.
