metroid prime pinball
Contra 4
Zelda

Tetris

these are all quality games

my picks are:
Advance Wars: Days of Ruin
The Legend of Zelda: Phantom Hourglass
Sonic Rush Adventure
Hotel Dusk: Room 215
Castlevania: Portrait of Ruin
Yoshi's Island DS
New Super Mario Bros.
Mario & Luigi: Partners in Time
Mario Kart DS

Puyo Pop Fever
Contra 4

Ooo I agree with Tetris, kept me entertained for ages

I don't have one, so I'm just going to say games that my little sister plays.

Harvest Moon: *Forgot main title*
Animal Crossing: *Apparently very popular*
