Good ds games

Final Fantasy Tactics A2

LoZ : Phantom Hourglass

Advance wars, either of them

I've only played it on Steam... but it was originally made for DS: Might & Magic: Clash of Heroes

very fun strategy / puzzle hybrid with an awesome story and a lengthy campaign :>

I liked TWEWY as well.

Been playing a lot of Dragon Quest 9 lately. The Zelda games for ds are quite fun also.

Picross 3D
Chrono Trigger
Mario Kart DS
Professor Layton Series
Scribblenauts
Space Invaders Extreme
Dragon Quest IX

"Fire Emblem: Shadow Dragon", "Harvest Moon", (don't judge me, it's relaxing, :P), "Dragon Quest IX", "Final Fantasy IV", and "Kirby Super Star Ultra".

999 and Hotel Dusk: Room 215

Pokemon :3(Mystery Dungeon has such as great story that made me cry, I don't cry even if I lose a close relative. so it's deep)
Super Mario 64 DS
Spectrobes(Not very famous game but is strangely fun and hard)

The Legend of Zelda: Spirit Tracks
The Legend of Zelda: Phantom Hourglass

looks like 999 is a good game, i will try it

Ace Attorney series.
