A new indie game that got released recently, has nice graphis and action and lots of freedom (including a "dev console" available in game for extras).
You create your own ship designs, stats, limited to a serie of skins though, which you can also mod with an in-game modding tool if needed.
You create your own universe, wether it's just 1 tiny galaxy few star systems or 6 different galaxy models in the same universe with a thousand stars. (or 10, or 20 galaxies, only limit is your PC)
Later on in the game, you can even generate planets or stars, improve your own, add floating continents or artificial planets, or ringworlds... and out of your planets, you can build fortresses, and make them roam the universe with ludicrous sized engines and use their planetary defence cannons and escort ships to annihilate your enemies.
