I have long thought about ways to make the board game of go (baduk, weiqi) more into a real-time srategy game. I found this game while doing research and it isn't quite it, but comes close.

I figured HN might be interested because it is one attempt at distilling the RTS genre down to just its core components: one resource, two unit types, a handful of types of terrain, a supply mechanic, unit health and morale rewarding micro.
