I'm enjoying it. I love how, on the surface, it just looks like yet another Risk clone, but in fact, is a lot more. I find it interesting that for the most part you just have to cohabitate in most regions with your opponents and actually wiping out of enemy troops only occurs pretty rarely and even then, usually just a single army at a time.
You're constantly juggling 3 aspects with each move, dominance of a region (what ever this game calls a single space) by having more units in it than any other opponent, dominance of a continent (what all of these regions of a single land mass combine into, obtained by owning the most regions therein), and points from set collection. As you can only purchase and immediately play 1 card per turn, and both your turns and cash in game are tightly limited, you need to find a card that somehow furthers your dominance or resource set goals, or at least will foil the plans of your opponents ("I'll bet you'd like that ruby card, Joe").
