DS games you recommend.

Wario Ware is a great laugh, as all Wario Ware games are. Castlevania: Portrait of Ruin is ace as well.

Yeah the Castlevanias are pure gold & I'd inlcude the GBA versions too.
Mario Kart is great & online is good too,
Mario vs DK 2 is sooo addictive & I love it!!,
And I always seem to want to go back to Brain Training, so I would include that too.

If u havent got a GBA then there are a few GBA games you should still consider too.
