Topic: New DS, New Games. Help!

So I've had the DS Fat since it's first release and never upgraded. I still love and use the brick but with the upcoming XL release I just so happen to have a couple $$ and have decided to spring for it. I don't need a discussion about whether or not I should get the XL, I rarely take my DS outside the house and when I do it goes in a suitcase. That said, I'd like to snag some new games to go along with my purchase but wanna make sure I'm getting some of the best the DS has to offer. I'm pretty much sold on Spirit Tracks and Bowser's Inside Story, and I already own:

Advance Wars Dual Strike
Brain Age 2
Bust A Move
Final Fantasy 3
Final Fantasy Tactics A2
Fire Emblem
Mariokart
Polarium
Prof. Layton 1 & 2
Super Mario 64
Warioware Touched
The World Ends With You
Yoshi's Island
Yoshi Touch & Go

So... what should I get?

Ace attorney investigations
Rhythm heaven (Awsome unless you've got no rhythm)
Kirby super star ultra
M&L partners in time (not as good as bowsers inside story but it's still good)
Pokemon Soul Silver (or Heart gold)
Wario ware DIY ( It looks awsome!)

That's all I can think of for now...

Save that money for some DSiWare!

This sounds like a job for the DS recommendations thread and DSiWare recommendations thread. :3
