So how do most of you feel about the fatigue/stress refresh rate in the game? As I read through the rules, and with no play experience to back me up, it feels like the refresh rate is pretty generous. I really want stress and fatigue to play a big role in my game. Any comments or suggestions are welcome.

It's fine for me.

In story mode, you need to not let it refresh, explaining that "all those shopping checks, rumour follow ups etc." for that week are piled together.

The three act (rally step recovery only between them) structure needs to be enforced, with each act having some menaces etc.
