In Handhelds

I take my DS to school often. I like playing multiplayer games (Currently Hooked on SM64 DS) and I am getting bored of them, Which kind do you reccomend (or think are cool) , preferibly SINGLE CARD DOWNLOAD PLAY games.

Around 85% of Muti-Play DS games have download play...Juts go to the store and check.

Mario Kart, but almost everything that is single card download is bvad compared to multiplayer card download.
