Would this be an expansion that adds a set of cards for a couple more modular parts of the game, like modular missions and assignments possibly?
This could be interesting but also challenging to balance since is could easily create missions that are too easy or too hard.
Lets stay on missions only for the sake of this thread. Each region or tier could get its own card or set of cards that set the length and possible events of the overall mission. It could be cool to set up a mystery path with the cards face down and decisions changing which cards get flipped or what path you take.
