Kinda brings up an interesting game to see how well-versed you are in the characters of Smash. List out all of the characters, and just identify whether you've played one of their main-series games, 'played' here meaning more than a few minute demo. Or do you really only know them from spin-offs? Or is Smash the only place you've ever experienced them? And this is just for fun, not a way to say "I've experienced everyone so I'm better than you," or "You haven't seen them at all, your opinions are trash."
(I'm counting the G&W Galleries)
