I was also excited about this game when I first read of it, not so much because I am a fan of Firefly (I enjoyed it, but not the biggest fan of the Western theme) as I was excited that it might be a module that could interface with the excellent GF9 Firefly board game (my favorite board game, hands down), that it might provide fun solo gaming experiences, or that it might at least offer a game system that could hand skirmish combat as well as stealth and negotiation tactics. Sadly, after reading through the rules, I cannot say I would ever want to play this game, as it does not tic a single one of those boxes for me. What is more, no matter how I approach it, it just doesn't seem fun. It seems more like a tabletop version of one of those mobile RPGs that does not give the player any advantage for strategy and tactics-rather, just keep mashing the button (or throwing dice) and eventually you will win.
I think GF9 missed the boat by not making this game compatible with the Firefly pick-up/delivery game. A working, fun combination could have been truly mind-blowing.
That's just my take. I hope others here get enjoyment from it!
