World War Air, Land and Sea
This is pretty much risk, but with planes and ships.
Planes attack all planes with 5vs6 dice.
Plus signs on the ships and land show attackable territories from that ship to land and from land to ship.
Ships attack the plane next to them with 6vs5 dice.
Ships attack other ships in there vicinity, but do not attack over land.
All other attacks are 6vs6 dice.
