Well, the sad thing is I only recently took our Freelancer server offline - as me and Maximus got bored with it. It will take 5 minutes to turn it back on again, so if you have the need for a space game now, I can always put it back up so we can give it a whirl. May even give me and Maximus a reason to play it again
It was a modified version of Freelancer - the Discovery
Mod, which among other things, allowed you to pilot capital ships and added loads of new systems. There are some links to it still at the bottom of the home page on this site - the Wiki is a good one to show you the kind of ships you can buy.
We did however, get to a point where we had shed-loads of money and nothing to spend it on so gave up.
I digress, I am really looking forward to Star Citizen - I just hope it is good as we haven't had a decent space sim in what seems like ages. Definitely check it out, but remember it is not scheduled for release until 2015!
