It is a really great game. I've played a bunch of times with Randy (the creator) with 3 or 4 people and each game has been different and challenging in new ways. It's one of those I appreciate more the more I play it. Can't wait to get my own copy!
Years ago a bought a game which was part of the Warhammer gamma and which featured the same approach. You'd build your own map out of the hexes, set the armies and conquer. :-)
