X3 is a great space game because you can go through missions and such, or you can just go do your own thing and build an empire. Heck, I'll post the link to the newest Star Wars mod too. Now that X3 is on GoG, I will post a link to the newest BSG mod I know of. I found some mods they recently started working on again. I posted this in the general discussion for anyone not familiar with the game, but am reposting it here by request.
