I have New Super Mario Bros and Metroid Prime Hunters, and am looking for more games to buy. I would easily recommend both games, though you should be warned that your hand *will* cramp up from Metroid Prime Hunters for at least the first couple of sessions. Honestly, I've found New Super Mario Bros to be more enjoyable than Mario 64 (N64 version, haven't played the DS version, though it'll probably be my next game).
