More generally -- are physical (board, pen-and-paper RPG, etc.) games OK? Or is this a jam just for video games?
For the same reasons as I stated before, we prefer you are at least able to make a video game. If you join and your giftee is cool with it, you could make a board game, but you have to be able to make a video game for if that's not the case.
I would guess video games but if you can ask your giftee!
