Rent Elebits! It's like a Katamari meets Ghostbusters. You have a gravity gun and throw shit all around the house, and you also rotate the beam to turn on faucets and open doors, and you can open refrigerators and ovens to look for the little alien dudes you're collecting. And as your gun gets stronger, you can pick up cars and launch then and stuff.
Edit: So far I've only used an SD card for 2 OPTIONAL things: showing slideshows on my Wii, and playing .mp3's during Excite Truck. You don't need one.
