1991, Psygnosis (of course), Commodore Amiga (double of course!): my little brother was 9 y/o at the time and we were teenagers and we'd play Lemmings like crazy on our Amiga.
My little couldn't speak english yes but he'd imitate the "oh, nooooo" sentence Lemmings you'd "suicide" would make.
More than three decades later my brother is still nicknamed "Lem" after "Lemmings" and that's how we call him. And about two decades ago, he gave his consulting company a name sounding like "Lemmings" (spelling slightly different). He's still "Lem" and he still has got that company.
Oh noooooooo!
