In my second game (or, actually, my first) Tonkin, I wanted to introduce a high level of interactivity and stress. This I solved by only allowing each player to conduct 1-3 actions before the opponent makes his 1-3 actions. An action could be to move a stack or make an attack or make a barrage etc. You never know, beforehand, if you will receive 1, 2 or 3 actions. Both players will eventually receive 10 actions per game turn, so if you receive to many "3:s" in the beginning and you don't save some of them, your opponent will be able to conduct a lot actions in a row in the end when yours are all spent.
