Consider your possible “cures” in the same way humans “cure” their blindness. If your dragon has cataracts, surgery could be an option if you could find a vet willing, able, and trained to do it. But if this is a natural degredation from age, there is no “cure.”
Tsuro is always our go-to short game for when folks are getting to game night and getting into the mood. We also like to play Uno at the end of the night when our brains are fried or Jackbox.
