Wanted to gather any F:AT thoughts on this. I just got my preorder this week and set up the tutorial. Seriously forget reading through the rules straight through, start with the playbook tutorial.
Anyway, haven't played much yet but my first instinct going through the rules is that I'm liking it better than Navajo Wars. Some of it is down to the situation---the Comanche were just straight up more warlike and so the game more closely resembles a more traditional wargame. You have bases that have leaders of different quality which activate bands of warriors to go fuck shit up. Anyway, I'm looking forward to trying it, it's making more sense to me than Navajo Wars.
Solitaire games aren't really my thing, but I picked it up based on the subject, and I'm really glad that I did. It's a little procedural, but not painfully so. Ultimately, this is still a game and not a puzzle with plenty of decisions to make and opportunities to mismanage resources.
I'm completely terrible at this btw, but it was pretty fun. Also, I heeded your advice on just jumping into the tutorial. I read through the rules afterward, which made learning it quite manageable. Did you prefer this to Navajo Wars?
