Well we got a ps1 when I was 7 I think, but I might have played some before then. Considering that was the most excited I've ever been I guess I must have known about video games before then. But the exact first time I found them I dunno. I used to play puzzle bobble on arcade machines a lot but that might have been after age 7 too, my memory before then about a lot of things is somewhat hazy like I have a handful of memories but not as consistent.
The first game I remember playing on the ps1 was Spyro the Dragon, but before playing that my dad started playing Abes Odyssey but then switched to Spyro because he seemed to decide it was more age appropriate I think (also the intro was disturbing lol.) Then again he showed me the Mr Creosote scene from Monty Python around that time, so he was an inconsistent judge of that.
I remember wishing my dad played more I guess so we could bond over that, but aside from that I didn't like watching people play games and preferred playing them. So I would sometimes hog the ps1 and because my brother always liked watching people play games, he sometimes didn't care. Then got into watching streamers etc later, he said I was the first one he watched haha.
Oh yeah and I'm pretty sure I played a game on an Acorn computer before that, it was the same year at school anyway. (There was one computer in the class, and we would have to share it in groups of 2 and pairs would have to alternate on different days, I can't remember if it was like a reward or something or not now.)
Also we had this computer at one point:

and there was some game that was a bit like Tetris but 3D, I always forget the name of, that I used to play.
