The one made by Digital Anvil and was developed by Chris Roberts who is making StarCitizen? And that Microsoft shut down it's servers and mods like Discovery Freelancer came about?
Yes probably that one, you seem to know a lot more about it than me.
I think it’s a bit obscure now, but I played that game a bunch when it was new. I really liked the concept, and approaching planets was really exciting. I never got really good at it though so I stopped playing after some point when I was unable to finish a mission anymore.
