Absolutely loving this game Black Market. It was in the last Championship bundle.
Unfortunately it's not on sale right now, but maybe it will before the winter sale is over. Basically the game consists of flying to different planets and space stations (just clicking on a map with lines between locations), picking up goods to buy low and sell high, and avoiding/killing pirates on the way. The battle system is limited, but pretty cool. If you get in a fight, the game turns into a side view battle (like a shmup) where you can move left and right and fire your weapons at the enemies above you.
The battles are a bit difficult at first, but once you salvage a good weapon, you can become pretty unstoppable. Thankfully, moving to the next system usually provides an immediate jump in difficulty, so it's not too easy all the time. Really though, what sets the game apart is its writing. You play as a trader named Vincent who has woken up with no memory and an eyepatch that is actually a cybernetic implant with a living AI inside it. I've actually laughed out loud more than once at this game. The writing (especially the dialogue) is good.
Definitely worth it for $2.50, or even $5. I wasn't expecting much and this game pleasantly surprised me.
You know I passed on this not being sure what it was. Now it sounds like a better version of one of my favorite games all time :(
Hopefully this pops up in another bundle soon.
