Darkstar One (Freelancer-Series)
Darkstar One offers a fantastic amount of freedom of choice. The story-based missions gradually lead you deeper into the galaxy to new races, new technologies and ever stronger opponents. Explore a vast array of solar systems in search of hidden artifacts of ancient races, essential objects for upgrading your ship–the Darkstar One.
Opinion
While I just had a breve look at the game, it is mentioned as one of newer alternatives to Freelancer.
For me it misses some charm, but might be worth a look for you.
