You know. The VGA is something I don't understand and would never do. But if people want to participate that's fine.
I count the VGA collecting as it's own subgenre that doesn't affect me. It's the same as the complete in box collectors. It's a whole different breed and most of the time doesn't affect prices outside. For example, I have been keeping an eye on Earthworm Jim for Game Gear. It won't sell for $10 loose. But boxed goes for $150.
If people want to form their own club of VGA collectors, that's fine. And props to the enterprising individual who gets 25-70 bucks for each game. They are a genius of capitalism.
I also have been collecting comics for years. Most people couldn't care less for CGC grading (comic equivalent of VGA). But some do and they spend A LOT more for those comics. But it's their money. They can do with it as they please.
