Check new novel about FreeSpace2. This is full trilogy from beginning to the end. http://www.fanfiction.net/s/9447114/1/
Here is first part of English translation. The other two parts are finished but still have been not translated.
I actually think Freespace did some things really well. It's hard to come back to - single location (muuuuuuch simpler to code as I'm learning) and some goopy controls, but it introduced the enemy threat in a more interesting way than WCP and FS2 had nice visuals. Not really interested in the universe though.
