Space Engineers on steam
If anyone has a creative urge and a bit of time to waste I would suggest trying this game on Steam. It's in alpha and the price is very low. Sandbox space construction game at present with more in depth gameplay to be developed. Very simple blocks to work with, cubes, pyramids and slopes, but everything you need to make almost any shape. Impressive physics and damage model, crashing your creations into asteroids has never been so much fun.
Here is my first serious creation, I had nothing to do today

I like stats

You can build a whole fleet of smaller fighters or whatever and park them on any flat metal surface. That's the next project when I have a day to waste
