Project::OSiRiON is a free space trading and combat simulation under development. Its goal is to create an immersive universe with open gameplay inspired by classic titles such as Elite, Privateer and Freelancer.

Was shared on the #Freegamer chat. Looks actually very good, and fully FOSS as well.
I played it a bit on the official (MMO like?) server and while it is early days obviously (Edit: well maybe not, seems like this project has been around much longer than I thought), the basics seem to be there. Controls and gameplay seems very Freelancer like.
