what ds and 3ds games are real good? i know about the mario and re revelations but lemme know if theres other cool stuff. i love platformers, shooters, action adventure. hate turn based rpgs though
Kid Icarus: Uprising is a great game; the Kingdom Hearts game is fairly solid as well. Mario Kart is good. Paper Mario and Professor Layton both just came out; I haven't really had time to spend with them but both have been well-regarded. If you don't have a Vita then the 3DS version of Virtue's Last Reward is a must-play, though you should try to play 999: Nine Hours, Nine Persons, Nine Doors for the DS first (one of the best games ever). Rhythm Thief and Theatrhythm are both cool if you like rhythm-based games. There are upgraded versions of two absolute classics in Ocarina of Time 3D and Starfox 64 3D, of course. Pushmo and Mighty Switch Force are a couple really good 3DS eShop games.
For the original DS... geez, there's so much! All the Castlevania games are superb, the Phoenix Wright series is good, the first four Professor Layton games (if you like puzzles), Contra 4 (fantastic action game), Ghost Trick, Hotel Dusk, the Kirby games (especially Canvas Curse and Mass Attack), the Wario Ware series, the Sonic Rush series, Retro Game Challenge (a total classic). Also if you like puzzles, the Picross games are personal favorites of mine. Oh, The World Ends With You! That's a great one.
This is getting pretty long, maybe I'll stop typing now.
