DS Daily: What do you desire?

Pocket Gamer issued some DS demands recently, with their list of titles that should already be on the handheld, but aren't. While they offered up some interesting candidates -- a good place to start the discussion -- we'd love to see you guys start throwing out ideas on all the games that could be. Sure, a GoldenEye or Mario Paint DS could be really excellent, but there are a lot of games out there. What do you think might benefit from the touchscreen, the WiFi, or both? Last time we discussed the what-ifs, we talked only about franchises ... but this time, anything's game.
