Atrocities, it is a space simulator with emphasis on RPG, trade and building your own interstellar corporation. And if this trade stuff is too boring for you, no problem, start pirate or bounty hunter carrer and hunt for greedy merchants and richy CEOs.
Reminds Starfury, but with much better graphics and really true 3d. Powerful comp required!
