Excellent game! Only two things I would suggest changing:
One, allow equipment to boost characters past the 10 skill max, otherwise some of it becomes relatively useless in the endgame.
Two, allow the option to not display otherwise occupied characters in the list when bringing up the list for a mission. Example: if I have people farming, I don't need them shown, grayed out, at the bottom of the list. The reason for this is that the huge number of people on a huge map causes a massive slowdown whenever one brings the list up.
Awesome game, regardless!
