New game or Wi-Fi?

[Guitar dude bill]

I'm kinda getting bored of Tetris DS on my own, so I'm not sure if I should get a different game, or get Wi-Fi to go online.

Any suggestions?

I'd get Wi-Fi. But I don't know where to get it.

I'd get Wi-Fi for now, then when you can get MKDS or Metroid Prime.
EDIT: Silky, you can get the USB Connecter(Dongle) I believe you can get it from the Nintendo Store. It will let you play online over Wi-Fi with Windows XP.
