Can someone recommend some DS games for me

[Lathum]

I know we have a big thread about it but I was just wondering if someone could recommend some games for me.

I like puzzle games like tetris, classic games and RPG's. Any suggestions are appreciated.

Professor Layton and the Diabolical Box (sequel to original)
Tetris DS
Planet Puzzle League
Meteos

[Marc Vaughan]

Professor Leyton (both)
Scribblenauts (great game imho - very unusual in basis and quite addictive)
Advance Wars (any and all)

Third the recommendation for Professor Layton and the Curious Village and Professor Layton and the Diabolical Box.

Also, a few more off the top of my head...
Picross DS
ChronoTrigger (remake of old JRPG)
Peggle (mindless fun)
Dragon Quest IV and V (remakes of old games)
Retro Game Challenge
if you like Final Fantasy, there are Final Fantasy III and IV (III was never released in the US til the DS version)
Any of the "Ace Attorney" games (Phoenix Wright or Apollo Justice)
Mario & Luigi: Partners in Time
Mario & Luigi: Bowser's Inside Story
Etrian Odyssey (old-school RPG that is almost pen and paper map-making style, is pretty hard but good)

If you like tactical strategy, I'd like to make a plug for Luminous Arc and Luminous Arc 2

Otherwise I'll second Chrono Trigger and Final Fantasy IV, but I can't in good faith recommend III. Was very disappointing.

Phoenix Wright Games are very fun as well, as TK says.
