Hi, DSS is an upcoming 4X RTS. Here's is the original announcement from April this year:
I am proud to present Deep Space Settlement! DSS is a real-time strategy game focused on empire building and grand-scale space battles. It is in development since February 2011 and is for PC Windows.
Story:
You are part of a multi-generational mission to colonize distant regions of space. Your journey brings you to a star cluster rich in resources and lightly populated. Or so it seems. Your goal is clear: setup a space settlement and thrive. Whether you choose to make allies or conquer through supremacy is up to you.
Features:
- Build your interstellar empire;
- Gather resources to power your empire economy;
- Trade resources between star-systems and players;

I am relatively far into development but there are still some features to implement. I hope to hit Alpha this summer
