I have to say my first game that I remember playing would have to be Duck Hunt for the original Nintendo at a friend's house. After that my parents bought me a Super Nintendo and played a ton of Super Mario World and Donkey Kong Country. Good times.
The very first game I remember playing was Crash Bash for the Playstation 1. I never owned the console when I was a child because my parents were stricty about not owning a video games console (althought that kinda backfired when they bought me my first PC and they didn't realise consoles aren't the only place where i can play games lmao).
So I used to go round to my friend's house annd play crash bash together for hours on end.
