Nearly 24 here xD
Some of the classics I've played were:
*Boulder Dash I & II
*The Games: Winter Edition

*The Games: Summer Edition
*Cops 'n' Robbers

*Pacman
*Popeye

*Paperboy

Those are the Commodore 64, we didn't have any more exciting games but these lot were great fun.
As for N64 classics, I greatly enjoyed Lylatwars (or Starfox 64 to the people overseas) and Smash Bros.
Other classics I enjoyed:
*Missile Command
*Centipede
*Pong
There's another game I liked from the Atari console but I cannot recall what it was...

I miss the C64

The family's C64 broke down so mum got rid of it. I hope to acquire another when I'm in a better house.
