1. What was the game or games that you ever played or owned?
2. How would you define your experience with those games and did they impact on your future preferences?

1. Starglider for the Atari ST
2. At the time I was blown away by that they got a fm soundchip to output singing
Can't say it impacted future preferences, sometimes wish I could play it again somehow

I think it was Super Mario World.

Crash Bandicoot 2: Cortex Strikes Back (PS1)

Good times.

The first game I remember playing is Crash Bandicoot. The most I remember reaching is the first boss who was that fat man who would hurl his stick or something round and you needed to avoid it. At the time I was maybe 3 years old and didn't get my first console ( a nes ) and own my first game until a year later. Crash Bandicoot helped define my gaming life in many ways but mainly it helped to lead me to the PlayStation ecosystem since this was the game which appealed to me the most as a child even after getting a nes, no game on the nes such as Super Mario Bros or Contra could appeal to me as much as Crash Bandicoot.

The first game I played was Advanced Dungeons&Dragons on Mattel Intellivision, I loved it !

The first game I remember playing was a BASIC text adventure. It was pretty small in hindsight, the object was to make a hot air balloon to escape where ever you were. That was in 1980.

First console game I owned was Konami Athletic land in 1984 on MSX.

To me it was as great as Wii Sports when it came out.
