I'm not a fan of racing games, however I would like to recommend Mario Kart. I'm terrible and frankly I'm not a fan of these sorts of games, however I would have to say that this game is absolutely hilarious when your playing with friends. Although this game can't be played with friends, another game I would recommend to play is Trauma Centre: Under the Knife. It's a sequel to it's original but you don't need to play the first one (I didn't). It's a surgery game, and I personally like to play this game a lot. It's a stylus game so there's not gonna be much button-jabbing action (unless you're speeding through endless dialogue >__>). If I think of anymore games I'll come back and post.
Actually, that's the first game. Trauma Centre: Under the Knife 2 is the sequel (on the DS). There's a Wii re-make and a Wii sequel too. But they're good games, yeah.
Blahh, I forgot to add the 2 XD. My bad but yeah what he said. The first game's graphics for the DS compared to it's sequel wasn't very good IMO. =/ Btw I've tried it on Wii; it's mad hard! Stitching people up = Floppin' your wrist in random directions
Coolest? Imho , Endless Frontier, The World Ends With You, SMT: Strange Journey, Rooms:The Main Building thats my cool list for now
Valkyrie Profile: Covenant of the Plume - I loved what they did with the VP spinoff. Actually i find it better than the PS1 original Custom Robo Arena - you control a freakin' robot, and you can put any part you want in it. There's nothing cooler than that!
TWEWY also sounds funny. TWEWY TWEWY TWEWY. Haahaha. LoL. I'm not sure if you will like The Sims 2 DS
