Not exactly in my 'childhood' but the first game I got hooked on was 'Asteroids'....there was an Arcade machine
in a shopping precinct and used to go 5-6 miles out my way to play it while the wife did the shopping! Happy Days!
Another too old child here - Subbuteo - table top football game where you had to flick the players to the ball with your index finger. Fantastically skillful game. Elite/Lords of Midnight for video games but I was moving into my twenties by then.
I used to go to school to play computer games, But it would have been games like Star Trek or Hamurabi.
Actually I was proper addicted to that Star Trek game. Did used to like text adventures and some acornsoft games, like Defender. Apart from that I think it was probably Elite that got me the most when it came out. Got a home computer pretty much just to play that.
