I choose snes as my favorite non-pc engine console. One of my alltime favorite games Super Metroid is featured and lots of other classics I like such as Super Turrican, Contra III, Street Fighter 2, Ganbare Goemon, Ultimate Parodious, Axelay etc. Im also very impressed by the powerful quality on Hardware and Software, I was very violent on my SNES stuff when I was a kid but still it never failed working no matter how much violence I gave it.
After that I add Sega Genesis, Saturn and Neo Geo as my other favorite non-NEC consoles.
