Space rebuild, station ownership.

Have you experienced the new content?
And if so, is it worth giving the game another look?

My gameplay has been so staggered throughout the last few years for this title, that I can't honestly say.
I played here and there but never locked into any of the new content.

However

Compared to the initial release, it is a majorly enhanced experience than it was originally.

If it's been a few years, I'd say try it. I'm actually tempted to do so, should a little free time occur.
