I was born in '92, but I had two older brothers born in '85 and '87, so I managed to piggyback on their gaming endeavours. I have memories of a lot of different games from when I was very young, but I struggle to place them in order - but whatever it was, it was definitely on either a NES or PC.
As for the NES, I only really recall Super Mario Bros. 1, 2, and 3 and some sort of 2D sidescrolling fantasy action game (where 5 year old me really struggled with the most basic of platforming). The NES broke at some point and never got fixed, so PC became the defacto gaming machine for a number of years until (I think) I got a PS1 for my 8th birthday.
We had that family PC as long as I can remember and those early PC gaming years had a real spread of games; the ones I can distinctly recall are Worms, Doom 2, Quake, Tomb Raider, Command and Conquer: Red Alert, the first Grand Theft Auto, and my very first personal PC game that I got for Christmas, The Simpsons Virtual Springfield (...I had fun at the time). I remember we also had some of these discs which offered 100 games in 1 which were generally super low-effort minigames, but that didn't stop 6 year old me from trying them all.
Talking about desktop pets conjured up a terrible memory - I almost certainly filled my family PC with malware trying to download some kind of virtual desktop stripper 😭 This is what happens when you let pre-pubescent boys have unrestricted access to the internet - it's probably the 90s equivalent of searching for booba on Youtube 😂 PS. I never actually got to see any boobs on that thing, it was all a ruse!
