I have several but it's been a while since I've played some of them.
I have an Atari 2600, Atari 5200, Atari 7800, Bally Astrocade, Intellivision, Coleco Telstar Arcade, Fairchild Channel F, Odyssey 2, Colecovision, Coleco Gemini, Intellivision II, Sears Video Arcade II, NES, Sega Master System, Super Nintendo, Super Nintendo 2, Super Famicom, Turbo Grafx 16, Nintendo 64, Sega Genesis, Genesis 2, Genesis 3, Sega 32X, Sega CD, Sega Saturn, Atari Jaguar, NES top loader, Dreamcast, Playstation, Virtual Boy, Playstation 2, Nintendo Gamecube, X-box, Playstation 3, and a Wii.
That's all I can think of, not counting hand held systems of course. I know there a couple of those that don't work anymore, and a couple of others that I haven't played in a least five years, but most are in good working condition.
I've never really understood the PC vs Console thing, some games are better when played on a console and some games are better when played on a PC.
