I’m not sure which one was first in order so I’ll just list them
My first console was Sega Mega Drive 2 (Genesis 2 in the US) with Lion King. I just recently read a thread where people said the giraffe and monkey level was so game breaking for them while I remember that I ran this level blind as a kid.
My school buddy’s sister had a NES with Super Mario Bros. and World Cup.
My first own PC was my uncle’s old 286 DOS PC which could run Prince of Persia in black and white.
On my uncle’s new PC i played Command & Conquer Tiberian Dawn for the first time which started my love for RTS games.
Edit: oh and my cousin had a C64 with Giana Sisters and Summer Olympics
