Thank you so much! You'll have to let us know how it goes with your group if you do get 4 to the table!
There is something to be said about simple rulesets. If you want to gather a few friends round for a quick one shot you don't want to spend half the session explaining how it works. With a survival or horror game, we wanted this to be as quick to jump in as possible.
Really appreciate your thoughts and kind words, thanks again :)
