My first game console had six games. One of them was 'tennis' aka Pong. Then there was squash (singles and doubles), which was Pong against a 'wall' and football, which was Pong with two bats each side. There were two light gun games. One with a bouncing square target, and another with a square target that went across the screen. Those never worked for me. You could make the bats small, and the ball speed up and the bounce angle sharper. Do all of them and that was hardcore. You weren't there, man, you didn't see it...
Then there was every game ever published for the Spectrum +3. Was I the only person who ever had one of those? Remember Bloodwych? The first ever Football Manager? Zoids (the crappy spectrum version - not the Commodore one)? The Magic Knight games? Novagen's Mercenary? Driller? Total Eclipse?
You can never go back.
