Probably Star Raiders on Atari. I remember the first game I was addicted to: Descent. Give me a plasma cannon and a handful of homing missiles and I'll whup your ass any day of the week.
Some sort of Helicopter shooter with Commodore-64. Must've been in -87 or -88.
The first game that I remember really liking is Stunt Car Racer on Amiga.
On the PC it would be the Olympic games of Seoul on my old '89 monochrome. That was when I was 3 1/2.
Then came Atari but I don't remember what game I played first on that. Probably the one with the duelling cowboys. I don't know if anyone remembers that game, but okay.
Then gameboy, as a Sinterklaas present... I think my first game on that was the Smurfs.
SNES, first game was this basketball game with Michael Jordan.
After that my first game on a computer with a pentium processor was Leisure Suit Larry
Oh yeah I remember Pole Position! (and of course everyone knows those other ones as well) I remember getting really pissed off every time I hit one of those doo-doo things or whatever they were. You know, those black spots on the road. But I was pretty damn good at it still (I mean playing, not hitting the black spots).
