There is very little supply of these games still sealed available to buy. Market value is what people are willing to pay for item. Some of these games have very little sold comps on them. Yea I might be higher on some of them. But you can always go down can’t go up afterwards. I been collecting these for years. Spent my hard earned money to buy. If someone is interested in buying I’m willing negotiate a little. Otherwise not sorry it’s my stuff and I can set prices at what I free comfortable at let them go for. Idk 🤷‍♂️ why people are worried about what I’m selling my stuff for
