One set of rules allowing you to play every period? We'll see about that. A quick game of Ancients (handled that pretty well), how about some WWII, Germans vs. US (really like what I am seeing), some VC vs. Marines, city fighting during the Tet Offensive/Battle of Hue (heart rate has increased), insurgents vs. Marines at Fallujah (SOLD!!).

This set of rules truly delivers on its claims, it is the only rule set you will ever need to play any period you want. I highly recommend it to anyone that does not game only one period and likes to transition between many. I love this game.
