[DS] Your Nintendo DS Library

Advance Wars: Dual Strike - Much better than the first two. I hated the first, for reference.
Animal Crossing: Wild World - The definitive DS game so far.
Asphalt: Urban GT - Stay away unless you're desperate.
Castlevania: Dawn of Sorrow - From what I've played, really really good.
Feel the Magic: XY/XX - It was great until rub rabbits (see The Rub Rabbits).
Kirby Canvas Curse - Not bad.
Mario & Luigi: Partners in Time - Super Mario RPG is still the best.
Mario Kart DS - One of the best Mario Karts, and online!
Mr. Driller Drill Spirits - At first I hated it but then I got used to it, and it's not bad. Lacks single-cart capability.
Nintendogs: Chihuahua & Friends - I love puppies.
Polarium - Meh.
Super Mario 64 DS - A worthy update.
The Rub Rabbits - Fantastic sequel to Feel the Magic. I'd say must-own but I realize a lot of people aren't into the whole minigame thing. But there's nothing quite like breaking the ice with girls by asking them to make babies with you!
Wario Ware Touched! - I got 999 in Zoo, that was pretty cool.
Yoshi Touch & Go - Mehhhhh.

Edit: The color coding system system is awful. You should change it to green being the highest and red being the worst; if you know a little about human perception you'll know that the area between green and yellow is the most visually attractive, so our eyes will dart there first (in theory). And this thread is relatively new, too.

Jam it back in, in the dark.
