EVN 3D is not possible, right?
what about the "Most Realistic Space Simulator" FreeSpace 2?
It's availiable for free if you want to creat a mod for it, however the missions you can make are more "Follow This ship destroy that one" type missions so you would not be able to have complex storylines
check this site out for more details.

Oh, Freespace 2. I have heard about that game, but the fact that's it has reached its tenth anniversary should be somewhat dismaying; it's too old to support a new fan base, in my opinion. Better to start with something newer.

I still play Pong. And Starcraft. Also, that's a broken link.

It's not "broken" per se, it just says one thing and does another.
