If someone bought a minigun and didnt like it they have to sell it for 50k, so they just lost 150k
The selling system will be able to make people more likely to buy items. Some people are afraid that if they buy an item and it's useless, it's permanent. With this system, then they can sell it so can still get some money back.
When will I ever see Python be used as a popular programming language?
I would never know.
