Humble Bundle gift link.
I've obtained many copies of the game to give out, so far I've given out 12 copies to friends on steam and have a few left, so I thought I would try one here.

"Take command of a vast interstellar empire and safeguard your species from total extinction in a procedurally generated 3D galaxy (with the option to flatten it) from 1 System to 10,000+! Prove your species' ingenuity through a deep and intricate combat system where anything (from individual components on ships to the stars themselves) is a target of opportunity. "

You can customize your ships, micro manage your civilization, expand into the universe, colonize thousands of planets in hundreds of solar systems, blow up planets, blow up stars, blow up the entire universe, shield your planets, move your planets, build ships as large as a solar system or three, research god like technology, and you can even mod the game. My favorite mod being Galactic Armory.
