I remember playing Naruto Ninja Council on a gameboy emulator on the PC as a kid. My uncle let me play a bit, and it was the middle of a boss fight with Brock Lee. I did not know how to move/fight at all, and died.
There was also this Jurassic Park game that I was bad at. I think at the start of some level, this annoying pterodactyl would catch you bring you to air, and I was just stuck with it because I didn't know what to do. Eventually, the character either gets brought to a dinosaur nest, or he uses a syringe on the pterodactyl to get down (if I mashed buttons enough). Now that I think of it, I'm not even sure if that was a Jurassic Park video game. I didn't even know about the franchise as a kid. All I remember about it was that it had dinosaurs, you played as a man (he probably a straw hat), it was a 2D side scroller (pixel art I think), and you had syringes and guns.
Lastly there was Alien. Another 2D side scroller, unlike the other 2 games I knew what I was doing (a bit). I identified the aliens as "goats" because that's what they looked like.
Another game I remember from early in my childhood was Jurassic Park for the Sega Genesis (also an emulator, also on my uncle's computer) had really vivid memories about being caught by a pterodactyl over and over again because I kept failing the level, and didn't know what to do because kids like me are bad at games. I would stay at a dinosaur nest after I slaughtered all of its children because I was terrified of the dinosaurs that existed beyond.
Lastly, there was Alien (probably the Sega Genesis too). As a bad as I was with games, at least in this one I remember being somewhat competent with this one, as in I don't just stay in location of the game and hope to not die. I still failed miserably though. I thought the aliens were "goats" because they looked like they were ramming, that's what I thought goats do as a kid.
The picture above shows a scene I remember vividly. Here is where the goat alien would ambush me. When I first played this part of the game I was surprised by it. In my next attempts of the level (if you thought I would finish this level, sorry, kids suck at games), I figured out I could go down the ladder, wait for the alien to come, and shoot him from below. It was the first time I figured out something in a video game, and I felt proud for it. Until the people stuck to the walls had aliens bursting out of them and I failed the level, that is.
Those were my earliest memories with games, sorry I couldn't just say firmly, "this was my first game", because I grew up with games during my childhood, and I had really bad memory from back then. Heck, I only knew Naruto Ninja Council because I played it later in my life, and the other 2 games only because I looked them up just now.
Still think Alien 3 is terrifying though.
