Inspired by Alex's Final Fantasy thread, which Nintendo games do you most feel are better than their ratings/reputation suggest, and what about them do you think makes them good?

All of their NES games. Yes, I know. They're classics. People respect them. But polling always has SNES versions above them... which I can understand from a certain point of view. After all, they're basically NES games with more polish. But those NES games, they invented the wheel, they didn't refine it. To be able to do what Nintendo did during that era, to dream all of those franchises up, and to do so at such a level as to still have sequels to them selling in the millions today? Simply unreal.

Luigi's Mansion (GameCube). I know it has a lot of fans, but I feel like there's still quite some people who consider it a bad game, and I had a lot of fun with it.

I would say Super Smash Bros. Brawl on Wii, but it's a fantastic game, and I only see Melee fanboys dumping it.
