Some of you may remember Realm - Fantasy Battles by Serious Lemon. It was a fantasy miniatures game that they produced. Then the game went away for a while. Well, it's back and now being made under the Creative Commons. The core of the rules has been pulled out, reworked, and turned into Full Command.
Full Command's rules are only 7 pages long and designed to be used for various modules. The first of which brings Realm - Fantasy Warfare back to your tabletop. Along with the game and module, Eureka Miniatures are creating an 18mm line of figures to go along with it.
