Very interesting!
A good strategic boardgame often has me thinking about warning the decisive actions (Almost like using the old GW mighty Empires game as a Warhammer campaign system) this weekend I played Liberty or Death (also by GOT, a COIN game) and after two years of small actions it all came down to a single large pitched battle in Massachusetts where French and patriot troops destroyed a British army at the onset of Winter. That and the French blockades pushed public opinion decisively toward open rebellion and the war was won.
GMT make some great Games!
