Why gribbly?

In 1997, id Software released Quake II, and I played a bunch of it. I was bad at it, but had a lot of fun!

Of course, to play Quake II you needed a screen name - and I picked one based on a formative game from my Commodore 64 childhood - Andrew Braybrook's 1985 gem "Gribbly's Day Out"

A grey cassette tape , label reads 'GRIBBLY'S DAY OUT for Commodore 64'

You can play it here on archive.org!
