Honestly, the game completely lacks any and all substance. It's bland, forgettable, boring and tedious.
In the game, you play as an unnamed adventurer/trader, that sets forth to do one thing, become the Master Trader of the known universe/galaxy. One of the first missions is to find some chick that will give you a million credits on loan in order for you to buy a ship and start trading. You have a deadline when to get the million credits needed, and this formula repeats itself several times throughout the game, so much so that even the multiplayer is basically only that. Oh, and no one plays the multiplayer. In order to GET the million credits, you have to buy some commodities on Earth, and go to the Moon (which is just clicking a button) and selling your merchandise. Or you can do contracts. More on that later.
The trading system is very simple. You get to one of the merchants, you see the commodities they have for sale, and you buy it. There is a bar graph showcasing whether the market price for the item is declining or not, however the graph is pretty much nonsense, seeing as there's no trend whatsoever, and seems to be entirely, 100% random. To add to that, the trading is a pretty pathetic source of income, as even if you get lucky, you won't really earn a huge profit on anything you sell.
You can also find random commodities strewn throughout the worlds you find yourself, so there's no real reason to actually BUY commodities, as you'll find some semi-valuable stuff just laying on the floor in the map, free for the taking. Items range from wool to fetuses and radioactive metals and whatnot, and the "illegal" stuff is more valuable than the legitimate trading commodities. The game doesn't punish you for owning or selling illegal commodities, which was a wasted opportunity for some amusing gameplay as an actual smuggler. Shame.
The second source of money is through doing contracts or helping people out with arduous tasks. To get a contract, you have to go to the bar, where the barman will give you a target which you have to kill. This is where the game gets a slight instance of gameplay, by introducing an FPS arena, however, this falls flat as well, because the gunplay is so barebones it physically hurts to play through the FPS stages. The missions where you help people out aren't much better, as the case often is that you're simply collecting or buying X commodity and bringing it to some random dude or chick. Again, incredibly tedious.
Also, the game came out 2008 if I'm not wrong. I originally thought it came out around 1999, when Freelancer came out, but holy ♥♥♥♥ 2008????????????????????????????????
The music is obnoxious and not memorable in any way (read: elevator music), it features abysmal graphics, the little mechanics the game has are horribly unrefined, the economic system is non functioning, trading is next to useless unless you get some very rare, expensive commodities from missions, and the entire game feels like a chore.
Overall, I'd give it a 3/10, would not recommend unless you have literally nothing else to do in your life.
