So I've been running Kingmaker and LOVING it.
I'm sure everyone has their own thing they do to facilitate running it, but I'd like to share what we are doing.
First, I printed out calendar pages, and the PCs are carefully counting days, writing events in the squares for each day, and it's turning out great.
The other thing we have been doing is this...

I've been awarding players who contribute traits related to ruling, or special gifts (our magistar just got an elk mount, for instance.)

If you have a dedicated enough party, this so far, has been a really great resource. I'd reccomend it to anyone.
