Since I recently bought a GB Micro I'm interested in re-discovering GBA's library, for some reason I largely ignored in comparison with other systems. Currently playing Super Mario Advance, which is pretty much the SNES version of SMB2 and I love it. I may buy the other Mario Advance games, but since I just went through NSMB2 and now SMA I'd like to play something different.
