Nintendo DS Recommendations.

[Saruk]

I am looking for some recommendations for games to get for my DS. Preferably not a full price DS game because I can't really afford to buy them at full price $30-$35.

I currently have Pokemon Platinum, Mario and Luigi Bowser's Inside Story, Kingom Hearts 358/2, New Super Mario Bros and Mario Kart DS.

I really need more games for my DS because I barely play it anymore after I beat all my current DS games. Any recommendations would be appreciated.
