My current game started with one of two colonists having asthma in both lungs. Since I haven't messed with organs yet, I decided to harvest the lungs from the first free colonist that joined, thinking I could replace Lumi's when I get a better doctor. I quickly realized organs are worth 300-500 silver a piece! Since I usually set my start conditions to having no silver or gold, this looked like easy cash! I proceeded to remove one lung, one kidney, then the heart of every surviving raider I capture. It slightly lowers all of the colonists mood when you do it, so you have to pace the operations. I only harvest the heart if I can handle the dead patient debuff. After 2 or 3 seasons of this I have increased one colonist's medical skill by 5 or 6 points, and when a trader finally comes along willing to buy them, I usually clean them out. I had to build a new prison/hospital wing to handle all the vicim... I mean... patients.

Anyone else toy with this strategy for making money early game? It's been a pretty fun so far. My colonists are basically Organ thieves selling stollen body parts on the black market. I think next time I'll try to get two psychopaths, so I don't have to deal with the mood penalties ;D
