No one is suggesting throwing away Neo stuff. But most people’s “collections” are hardly museum grade or of significant value.
If I had MS1 on home art I’d sell it, buy the game on MVS, and use the cash remaining to buy real estate.
Perfect, now we have finally solved every doubt about it: I've recommended caution, because many people who pulled their plug on the video game world decades ago, don't realize the value of their items.
I'll tell you this true story:
Once a guy was emptying his attic and had found some Snes games he had bought at the time and among them there was also 'Hagane' in Pal version: not knowing what to do with it he wanted to throw it away, but then he preferred to give it to a friend of his and this original owner never knew that he had lost forever several hundred dollars.
How about NCAA College Basketball 2K3 for the Gamecube?
I don't know if my comment offended you because you are a fan of this series, but in any case it was not my intention.
However, the high prices of the used market essentially depend on two factors: quantity and demand.
Games like the aforementioned 'NHL' and 'NBA 2K' sell several million copies every year and also have an audience not very interested in the integral preservation of past titles, for all these reasons, the games of these series sometimes in the used market they don't even cost two dollars, while for the 'NCAA College Basketball 2K3' you mentioned, there is to say that Sega and Nintendo for the GameCube version have printed very few copies and that is why it costs so much, because with such a scarce availability, it will not never be possible satisfy all the possible collectors eager to get this game.
