this is the dicussion forum. what you posted was a spoiler and shuld go in the spoiler forum. not only that but this has been said about a million times. If you bothered to LOOK in the spoiler forum you would of known this though. welcome to the forums anyway... please read the sticky that says somthing like "read this thread before posting".

If I had a nickel for every time someone told me that my idea for melting down coins to make a giant robotic parrot was a bad idea, I would have one kicka$$ giant robotic parrot.

well, that is one of the unknown systems (I won't tell you how much there are around, since that would be a spoiler ). Someone correct me if I'm wrong, but I do not think you can buy stuff from them ... in that system, you get to kill nomads and get stuff from them (weapons).

The planets seem to be there so you can ... land to save the game and to ilustrate a scary system

I do believe you can sell things on those planets, but the prices they have (at least for commodities) are quite bad ... sell products somewhere else ...
