Hey all, I'm starting to use my DS a lot more, what are some DS games where I can get the most for my money?

PS - I don't use the Wi-fi online modes since the first DS does not support WPA-PSK 2 Enterprise encryption =(

That game, with, mario...

I'm a huge fan of Osu! Tatakae! Ouendan (I played a lot of a friend's copy).  There's a sequel out in Japan, but I haven't played that one.  Those two are on my buy list.

Other than that... well, I checked out your GameSpot game list and you own a pathetic number of DS games.  I recommend Mario Kart DS (best Mario Kart), WarioWare Touched! (it's short but fun), and if you can get it free get Yoshi Touch & Go.  Touch & Go is fun, but it can get old fast.  Also, if you really like Super Mario 64 go ahead and pick up the DS version.  It's still fun.

The easy choice for best value is Mario Kart DS.  I spent a whole bunch of time in that game.
