A good board game for the season? I'm glad you asked! Pandemic-Reign of Cthulhu was released late last year to good reviews, but quickly disappeared from the mainstream amid all the other great releases. Often overlooked, it is a solid go-to game for us.
A Cthulhu re-do of Pandemic is not something I thought would have worked. But it succeeds in both theme and gameplay. Instead of the world-spanning crisis of Pandemic, the scope has been limited to four cities in the lore (Arkham, Kingsport, Dunwich, and Innsmouth.) 1-4 players draw a investigator and try to seal the gates before Cthulhu is awakened and all is lost.
I like Reign of Cthulhu a little better than Standard Pandemic. Obviously it's the theme, but I feel that being a zoomed-in level it offers a bit more detail. Gameplay flows better for me as well. There are plenty of good in-depth reviews out on Boardgame Geek and Youtube if you would like a deeper dive into the rules.
It a good choice to put upon the table and try and save the world in between waves of Trick or Treaters.
