oof, I’d fail trivia questions for my age group because I had a… complicated childhood. But it would probably be a problem for foreigners who didn’t grow up the country. Imagine coming from Chile and having to know about Australian trivia from the 70s or something to sign up for a social media platform 😄
Is the idea for just the game to be FOSS or for the characters to be related to FOSS as well? IMO, the latter would be a good limitation to start with, which would be in the vein of Super Tux Kart using FOSS mascots.
