The first game I ever played is probably Duckhunt.
But I mainly started getting a bit more into games when we got a PS1. I played a lot of Need for Speed (a few different ones) with my parents. And I also had (and still have) the original Guilty Gear for PS1. Those got me pretty into racing and fighting games, which is the preference I still had by the time I got a PS2 (slim). Aaaaand then I tried Final Fantasy IX. That was the first game that actually had an impact on me, as far as games go. It was, and still is, amazing to me.
