Occasionally I retro game with my Commodore 64. Thats about as close as I come to retro console gaming. Yes, for all practical purposes it is a console. It has a cartridge slot in the back but all of my "cartridge games" were converted to 5 1/4-inch floppy and I have a pretty wide selection of "coin op" games ported to the C64 including Pac Man, Ms Pacman, Donkey Kong, Dig Dug, Galaxian, Galaga, Pole Position, Defender, Robotron, etc. Also some other cool games including: Jump Man, Gold Runner, Seven City's of Gold, Drelbs, Stellar 7, Raid on Bungling Bay, M.U.L.E., Zaxxon, Blue Max, Moon Patrol, and a few other titles I can't remember. A few of the games won't work but most still do!
If some people are like me, they have a hard time retro gaming games which they didn't play originally back in the day. For example, people say Zelda: Ocarina of Time is amazing, but since I first played Wind Waker, OoT looks clunky and dated and as much as I've tried, I can't get into it. It is probably like that for people who got spoiled with newer games first, and can't go backwards. But I find myself drawn now and then to old fond games of the past, and enjoy them still, despite their primitive graphics, as long as the game play is fun.
