<geek alert> I have pong with paddles, Atari 2600 still in it box, lost the joysticks because I used to use them on my Vic 20 then C128 which I still have with Disk Drive plus all the games. I also have Sega master system in the loft, Mega Drive bits of PC's and complete PCs which now used as servers running linux, but now I own 360 as its just easier than upgrading for every new game that comes out.
best retro game for me was Elite, such a massive game, head over tails, Wizball, Bruce Lee, Green Beret, Saxon, Paradriod and uridium possible the greatest shooter ever made
