As a hobby only at the moment, ultimately to give it away free/cheap, but it consumes my head so much I do ponder about other potential for it. One of those is its K-12 educational potential (in an alternate non-game mode) but I currently know next-to-nothing about the educational software market.

It's cross-platform OpenGL (C++ & Lua) and is basically a "unit-less" RTS with a planetary sciences bent. I'm enjoying every second of developing it.
