just bought the game, now i have a few questions

[wilhil]

Hi

just got the game, and as with every game i have some questions that i could not figure out.

is there any sort of mechanism that records friends/enemys apart from when you are on a mission, I mean enemies from the beggining will they always fire on you whenever they can? or by firing on their enemys do they become your friends....

and also question on buying and selling excluding comodities. does everything always sell for the price, and you buy everything the same on any planet, or base?

when you sell ships to upgrade, do you always get half vaue back?

I think that is all for now!
