So as a comic and game collector nostalgia takes the biggest part of this. Unfortunately the way the market is everyone that is a perfectionist has raised the value of them higher and higher needing the mint most perfect ones. For comics the grading concept is a great idea for older comics to help preserve them from deteriorating but grading new comics is pointless.(unless your only a reseller and have no love for the industry and prefers greed over the community) but most books should be read and enjoyed. The same goes to video games if a game is sealed or is a one of a kind prototype then grading is fine for the preservation of the games. Grading cib or loose games I feel is a joke the people who do that are just out for the money and don’t care about the true love and joy of the games. Now as time has continued the use of ROMS has been more and more so you can still play the games but the collectors market has definitely started shifting. I have also noticed many horders have been stock piling selected games making certain games more desirable like key comics.
Ocourse this is just my opinion
