I know about grading sport cards services like Beckett?s BSG or PSA and grading comic books. I used to collect hockey and basketball cards, then send some valuable cards for grading to increase its value and proof the card is not counterfeit. Now someone is grading old video games. Video Game Authority is now grading old games and sealing them away in a tamper-proof case that will tell buyers the exact condition of the game they are buying. Some gaming fans might find it interesting, but I think this game authority a little overwhelming.

I don’t really understand what you mean by “grading.” Do they grade the game out of 100 or something? I’ve never even heard about this before, it sounds interesting and a bit odd, haha.
