Mario Kart - Double Dash (8 player is absolutely insane.)
I thouroughly enjoyed Zelda also, and currently Naruto 2.
I don't know, I couldn't get into Eternal Darkness. I found the camera extremely annoying, and I really hated not knowing WTF to do or where to go. I never finished it and sold it off.
Metroid, I couldn't get into too much either though I did finish it. But that has never been my type of game... never a major fan of the Metroid series.
I want to pick up Viewtiful Joe when its cheap ($20 or less). I played the demo and it was very good.
