I had Atari 2600 when I was a kid. Ah such fond memories!
Got a Commodore 64 when I was around 8-9 and enjoyed all the turbo cassettes and "load", and "run" commandos to get the games started.
About 3 years later I got an Amiga 500. While I had that one I got back into the console world with a Sega Genesis. It was not as fun as the Amiga, though, so I gave it to my nieces. I still have the Amiga in working condition and I take it out of storage sometimes and play old classics. The Amiga might not be a console, but as a computer it was mostly focused on gaming.
After I gave away the Genesis. I have stayed away from the console world until last year when I got a used Sega Dreamcast off Ebay on a whim and it has been great fun. The Dreamcast was a great console and almost 10 years after it was canceled, its games are still fun and engaging to play. Especially multiplayer "the old way" (i.e. all the players are physically in the same room).
I burned a CD with a NES emulator for my wife to relive old games from her childhood when she played on her brothers Famicom. For me it's Dreamcast FTW!
