My bad indeed, what I ment was minimal ingame purchases.
With trasfering credits between accounts I thought that was patched up? Sry for off topic.
Here's a thought about selling engineered stuff (from lore pount of view). The thing is, like I said before, it would change the concept of engineeres, after all they are Secretive individuals who I'd assume do not like sharing their knowledge freely. If the said mechanic of selling the engineered stuff was made say illegal BUT available, say black marked for parts, and then say those parts are tagged as illicit and when scanned by security the player gets fine or bounty... that would sound like an interesting conceot to me. One would have to wheigh pros and cons of taking route of aquireing said parts. Either easy but pottentialy hazardous, or hard way but safer. From role play perspective, that would be ace. A pirate would not give a flying about having legal parts, same for deep space explorer... I would defo be up for that like.
