How light hearted and/or meta can we go with this i.e. could I be Patrick Star or a deck of cards from solitaire, the Linux Penguin, etc. And indeed what constitutes a game? I.e. would clippy or bonzi buddy count? Or the computer of Zork? Regardless fairly interested in this and once some reading is done and questions answered I will work on a sheet this weekend

Hey there, glad to see you're interested!

Your character can be lighthearted, but must be both a character and a character that originated from a game, so all the examples you listed would not qualify. It's difficult to qualify what exactly makes a game (for instance, saying digital media for entertainment purposes that necessitates interaction from a player would no doubt have loopholes), but I can go on a case by case basis if need be.
