It's just a completely arbitrary line between comics and games. I don't own a comic, I've never read one and I don't give two shits about them. Yet, Wata copies the comic scale and heavily markets video games as the next big thing at comic trade shows. So what do you know, a comic guy comes in and tells his friends, they recruit more, the ponzi scheme continues, yadda yadda yadda. It's about artificial acceleration of the hobby due to actively recruiting new money, many of which have absolutely no eye for condition or rarity as evident with a lot of sale prices.
It's obviously a strategic move, as copying the coin scale and marketing to coin guys would have been futile due to demographic differences, and copying the card scale / marketing at card shows may not have made as much sense for a 3D item vs. 2D. But still, while we all collect video games, there's other collectibles like sports memorabilia, vintage toys, art, sneakers, etc. The new money could have been sold on anything other than games, but we injected them here.
For as hot as we think games are, sneakers are even more ridiculous. StockX ( http://www.stockx.com ) has literally turned sneaker collecting into a multi billion dollar online stock marketplace, they even had a SuperBowl ad last year. Wata and HA are still chump change compared to the genius entrepreneur that put together StockX... which coincidentally, is also expanding to other collectibles. Maybe video games will be on there someday too...
Either way, I assume most collectors expect their collection to go up in value. But when it just blows up so stupidly it takes a lot of fun out of it. So what, a lot of us had a good year selling, it's just money. But it certainly makes it a lot more difficult to collect, which I assume is what most collectors like to do. Normal organic growth is great, injected money is not.
