At school:
A few adventure games on the BBCs
Space Invaders
At home:
Centipede
Asteriods
Missile Command
"Soccer"
Leaper
Cops & Robbers
Awesome side-scrolling shooter (DefenderII?)
There was a sort of 1st person Asteriods too.
On an
Atari 65xe.
The games came on cassette tapes and cost £1-5 each. Took about 5-10 minutes to (sometimes) load and they made a horrible screechy noise.
Then sega came into my house and started charging £30 a pop.
