Just stumbled upon this early stage game. Looks really promising. I think it's the closest to SC from all the space games out there. They are due to release a Steam early access version, at the beginning of 2017. I'm definitely getting it. I really like the fact they decided not to go for a crowd funding development strategy. Too many developers doing that nowadays, and most of them are only delivering beautiful core ideas, buried under huge piles of the shittiest design choices.
