Between StarStrike and Brush War, I knocked together a basic framework for ww2 (and possibly beyond) platoon level skirmish.
It's only 3 pages but if you are curious, give it a look and let me know if it's something that's worth building out more or if it's too weird.
Note that this isn't really a replacement for FiveCore or In Sight, as much as a possible third "leg" of game engines to build things for. Think of it as a tech demo :)
Comment or email with what you think. If anyone can get some figures on the table and test, that'd be even better.
