Khuutra and tehsage are right. The Ace Attorney games are awesome.
As for Call of Duty. I am only aware of one being on DS, and that's Modern Warfare. I played the single player once and it was pretty fun. As for multiplayer, I'm not sure if it's in the game or not but if it is and it's online, I'd imagine it would be as functional as Mario Kart DS.
