Nintendo DS - Missing any must-have games?

[bobbyi]

Castlevania: Dawn of Sorrows is must-have. I really loved that game. It's actually the only Castlevania game I've ever played all the way through.

I've heard people say that Advance Wars is must-have also, but I haven't played that myself yet.

Sonic Rush and Kirby are both fun well-designed quick games that are easily worth picking up for $20.
