The last game I ran did have a week of downtime because one PC's wounds got infected and no one in the party had any healing magic (and later a month and a half of downtime because one PC was critically wounded and the same thing, no healing magic), and I know several times they made camp in mid-afternoon because they were all exhausted from riding hours in the rain. I am the kind of GM who loves rules for cholera.

I loved Birthright's setting--especially its version of elves and the existence of awnsheghlien--but the rules feel like two games laid on top of each other, the adventurer game and the domain ruling game, with barely any interaction between them.
