Best game for Nintendo DS?

No, not the new Zelda. Check out this game where you have to screw with Daffy Duck. I really want to try this one.

You spend the game pissing off Daffy until you trigger a mini game where you thwart his efforts to do whatever he\'s trying to do.

The new Zelda is very polished, very fun. Also very easy.

The game that had eaten me alive until Zelda came out was Brain Age 2. Just the Sudoku alone must have 40-50 hours logged in.
