X-Mass for 10 yr old Boy

Hello everyone. I needed some help with picking out some games for my 10 year old son, so I figured I'd visit here and ask the Experts.

I've gotten him the DS for X-Mass and I also picked up Super Mario 64 DS. I've heard that the game is kinda a turd, but he did ask for that game from Santa. Now I'd like to score him a few games that are hopefully better than that one. Can ya'll suggest a few titles that you think he would enjoy? He loves Mario and Spyro, but any game that is quality can hold his attention. I'd also prefer that the titles brought up be older titles so I can score them used. He has no experience with the system, so anything is new to him.

Thanks in advance, and please bear in mind that the gamer is a 10 yr old.

1. Mario 64 DS is an amazing game.
