Knights Side-Quest 07: Grading Video Games

In this special Peter (Retrogamepapa) together with Max and Michiel discuss the grading of video games. Why do people do it? Why do these companies exist? Slight spoiler: Max has a different opinion than Michiel and Peter have on grading video games...

Next to discussing graded games, they also talk a bit about owning and/or keeping games sealed. This is something which is almost inherently linked to grading video games. Is there actually a difference between the two in regards to why? For which reasons do people keep games sealed? So many questions... It's all talked about in this side-quest!
