I Just bought a DS.... I need some game recommendations :)

[loadedstatement]

Here are the games I have comments on:

Any training/brain age game - You'll know if you are into these. Im not, but a ton of people are.
Nintendogs - Same thing. I dont like them, others do. Think virtual pet though.
Mario Kart DS - If you like the franchise, it is a neat game. Online play. Missions, Cups, etc. I really enjoy this game.
Kirby's Canvas Curse - Good game. Not conventional Kirby though. Completely controlled w/ the stylus. I would check out gameplay videos to see how it is played. 
Super Mario 64 DS - Port of the 64 game. If you have a Wii, its on the VC for about $8 I think. 
Castlevania: Portrait of Ruin- I really enjoyed this game. Zombie killer game. Ive heard the other Castlevania DS title is better, but I enjoyed this one too.
Jump Ultimate Stars - Great game if you want an import. it is in all Japanese. It is basically a Smash Bros with anime characters. If anime and japanes isnt your thing, you wouldnt like this.
New Super Mario Bros - Good, clean fun. Just a mario side scroller. It was fairly easy, but I didnt mind. So was Galaxy.
Zelda Phantom Hourglass - You are getting it. And you'll love it.
WarioWare Touched - Fun little minigames. If you have played WarioWare games before, you know what to expect.
Elite Beat Agents - a fun rhythm game. 
Ouendan - This is basically Elite Beat Agents in japan. Another import and offers the same kind of gameplay. If you love Elite Beat, Ouendan may be a game for you (it has more titles in the series). Once again, all Japanese.


That is all I can remember right now. If you have questions on any game I mentioned or any other game that isnt on here, ask away. I've completed all the games I mentioned above in their entireties.
