Fire Emblem is pretty spiffy if you like turn-based strategy. Super Monkey Ball 2 for the Gamecube is the best incarnation of Monkey Ball -- the PS2 port had terrible framerate and control issues, and the Wii Monkey Ball has received poor reviews. Megaman X Collection is pretty good, all the X games were great. If you have a PS2, I recommend the PS2 version as the DualShock controller is easier to use for a platformer. Wind Waker, Mario Sunshine, Metroid Prime. MP: Echoes isn't as good as the original, but it's still good, get it if you love MP. Oh, and if someone tells you you should get StarFox Adventures... they're just pulling your chain. Avoid this one at all costs.
