Kristin got me a GBA SP for my upcoming birthday and anniversary, cause she is so cool. I have to say it is a pretty cool little machine, so far I only have Metroid Fusion, and I have ordered Advance Wars, which I hear is one of the best. The size is great very small, it is about the size of a 1 + 1/2 business cards and about 1" think. Screen light is killer and playing these old SNES style games is great so far and a great contrast to the cube. I have not hooked it up to the cube yet but plan to with the cable and Zelda and see whats up. So the games I think I should get are:

1. Advance Wars
2. Metroid Fusion
3. Super Mario World: Super Mario Advance 2
4. Konami Collector's Series: Arcade Advanced
5. Street Fighter Alpha 3
6. Colin McRae Rally 2.0
