Lighting and textures in a Space Sim

I'm trying to make a 3D space sim - similiar to Master of Orion or Sins of a Solar Empire. Should i just use Unity's 1st or 3rd person controller or would it be worth the hastle of creating my own? And how do I simulate the blackness of space - just apply dark textures to a skybox? Anyone know of a tutorial on the subject?

Here is a tut on how to make a skybox:

And here is a code to make a good smooth follow that is designed for space ships:

I found that the one above did not work near as well as this one, though with this one you have to add your own tilting when you turn corners:

I find it easier to take someone elses codes and just add to them.

Hope this helps!!!
