What is the name of the following game?

A friend of mine once played a game in which you built with blocks like Minecraft. However, the game was a little more about technology. So I could build shield generators or a drive (at least my buddy who built a star destroyer I think did that). Does anyone know what this game is called, how much it costs and where to get it?

There are modpacks like Feed The Beast or Tekkit which have a lot of technology and magic.

But I'm not sure if you mean that

The description sounds like eco.
