Hey, I have Darkstar One for PC.
Don't get your hopes up. It's outstandingly average, and full of ill defined aliens, who exist to go "ooo, I'm an alien! This game is set in SPACE!"
Also, all the space pirates talked with funny accents. Mainly Irish. "Oh top o' the mornin' to ya, we're takin yer cargo". With bad voice acting. And an irritating "love interest" sidekick, who of course gets kidnapped.
Also, it had a shitty ship leveling up system and very linear weapon progression- human space has shitty lasers, and the further away you go from human space, the better weapons become. But you can't use them unless you get artifacts, which pretty much mean that money is irrelevant, because there are a limited amount of artifacts (all in scripted locations, no randomisation), and you need more to get a level up and use better weapons. Yeah. Your ship gains levels. THE SHIP. Not the character, the ship. It adapts, or some bullshit, using artifacts as a resource.
EDIT: you can hear the Irish pirates, about 43 seconds in. It looks like the exact same game. Exact. Same ship, same graphics, same voice acting, same irritating main character and love interest (that's them on the box at the end). It's a bad game.
If you want a good space sim, get X3: Terran Conflict. Darkstar one is just like it, but with all the depth stripped out.
