Although I own a SNES, Genesis, Turbografx-16, Atari 800, and Nintendo 64, I would give them all up for the gameboy series of portables. Between the classic game boy games, the color, and the GBA carts, you get a great cross section of gaming from 1989-2008. I currently own 4 GBA advances. I particularly love the artwork on the cartridges of the classic gameboy games. Nemesis is one of my all time favorite games for the gameboy.
