It has similarities to both risk and A/A. You have specific military pieces (land/air, and naval in the expansion) that you can build each turn and then attack with, but it has a diplomacy aspect too, to take over countries and influence minor nations.
The die rolling system isn’t number based, but is based on icons of the units on each die. If you roll for the fighters and get a fighter icon up on the die, they score a hit.
It is an interesting concept. Haven’t played it much, can’t get the group to move off of A/A, but we’ve thought of taking the map (which when you put the regular and expansions together is about 1/4 bigger than A/A) and using it for A/A, and using the extra pieces as extras. Alas, no transports or bombers. arrrgh… so we just bought more A/A pieces…
