Yes my Neo has been my favorite system of all time. Fighting game slice of heaven, great shooters, and a few nice platformers. Long after SNKP retires the NEO, will it still sit on top of my entertainment center as well as anyone else who reveres 2D fighting games so much. I wonder how homecart prices will be like 10 years from now.
Runner up: Genesis and all its mutations. So many great shooters, the Shinobi series, Golden Axe, SOR, and Phantasy Star 2-4 as well as on Sega CD; Snatcher, more shooters, Lunar, and on 32X, the awesome Afterburner Complete and Shadow Squadron.
Third place: The good ol NES.
SNES wasn't named b/c I never owned one, my brother did.
