F1. Survive 1 is Absolutely Lethal
It's so lethal, I had difficulty enjoying the two games that I played at Survive 1. They were absolutely lethal, and died almost immediately. I spent longer creating the character than I did playing the game. It seems like the only possible way of banking the shot, is to get a bug out bag early on, and then get to 15 grit so that you can raise your Survive to 2, (which: wow, even playing at Survive 2, ...) or getting an antiquated toolkit, so that you can survive maybe one more encounter, ...
In my last game I played, I started with the following sentence: "Roll 3d6, and assign each d6 to Fight, Persuade, or Survive, recording the value." That made the game way more fun for me. I also rolled Mission Generation & Home before assigning d6's, so that I could make a character that felt more appropriate to the background.
F2. Reusing the Hex Map is Cool
I found that if I reused the same hex map for the multiple games, it created a greater sense of immersion and ecology. Each of the x6 home locations is on there. Interesting but more tricky is placing the x6 different Mission Generation locations on there -- the Settlement, the Monument, the Ruin, the Works, the Rich, and the Anomaly. The problem only arises with the Winnebago, depending on how it works.
