The very first videogame i played was a variant of pong. It was on one of those multi-games (all being variant of pongs actually) antique consoles from the 2nd part of the seventies.
The first videogame i played on a computer was
Space shuttle simulator on an antique computer called MO5, probably what started my love for space simulations that lead me in playing with Orbiter so much nowadays.
Much later, i think the game that addicted me the most was
Hunter on an Atari ST , it was utterly awesome, never played anything like this before, probably why it made such an impression on me.
I got a PC rather late, and the first PC game i played was Daggerfall, it's basically why i worked to be able to afford a PC at the time, reading the review on various magazines had me really hooked in this.
While it wasn't as amazing as i imagined it to be, i still played this game for an immense amount of time.
When i think about my youth, it's rather impressive how gaming technology has improved.
But in the same time, it's odd but what i play nowadays are not actually use modern technology for the visuals and some of them are even rather low res 2D or even ASCII.
And the heavy majority of games i play are free and/or open sourced ones, out of M&B Warband, i don't even remember when was it that a commercial game attracted my attention so much that i purchased it.
Without even mentionning that i still play some (very) oldies thanks to DOSBox, i guess modern videogaming didn't attracted me at all if i am still playing those, fortunately still enjoying my time with them
though finding free time is not as easy anymore.
