I love the "partnered" surveys (I mean, I'm at least partly responsible for starting it), so I'd love another game working off of that idea. I like the idea of questions like on those game shows, because it would be interesting to explore what the characters get right and what they get wrong, although that might get problematic sometimes. If you want to do "physical challenges", I'd just make them be simple writing prompts using the two characters (maybe a mix of the two?). I'm also not sure I like the idea of using points, because I like when I'm basically competing against myself rather than against the other people on the board, but it could work.
Anyway, I'm always open to more games, and even though I'm not sure how to work out the kinks for this idea, it has a lot of potential and if you can figure out a way to make it work, I'll gladly play.
