TTRPG using Uno cards

There's a bunch of fun, lightweight TTRPG systems out there that are exploring using more common gaming tools (partly because they're cheaper and easier to find than D&D rulebooks and such), and I thought it would be fun to try designing one on my own!

( The basic rules )

( Optional: Playing card variation )

I think that covers all the Uno cards in an average deck? I looked them up online, and that's what the website says they have, at any rate.

Feedback welcome! This includes such feedback as, "Oh hey, Socchan, it looks like you accidentally reinvented a TTRPG system that already exists! Here's a link so you can find out more about that one," and also, "Uh, you completely forgot about this particular aspect of play???"

Hmmm....

I wanna sign up for mlsquaredance for the exchange, but I need to figure out which fics would even work. Only one of them can be a smut fic, and that's kinda what I have the most of that's not like. Blatantly reveling in identity reveals? Under Cover(s) would probably work, but that was very heavily influenced by my podficcing partner, and I think I'd want her permission/blessing before I offered it up either way.

Maybe I should just sign up for the Buffet version and leave it at that...
