Well... it was fun in the beginning.
I played with friends, but it's also fun playing on your own.
many places to go, a lot of systems and planets to visit.
but you have 3 main alien races. and that's it. quests are the same and you get to do the same things over and over...
the story is nice but I have done all is needed pretty fast.
right now I am at the "must complete all achievements" phase, and that's just exhausting 
if you get it for free or in a nice sale, try it. it's not worth the full price.
was hoping SC will come out for PlayStation since that's the only place I can still play with a wife and a kid
