So here is today's lesson in how stupid games become stupid expensive. I noticed this since I've gotten back into Wii collecting.
Basically what people do is go on vgchartz, pick out a console, scroll down and look at what games sold like crap. Buy said games (or even horde them), then go around the net (in particular, Youtube) boasting about how they are "the rarest games ever for system x", and then proceed to watch prices go insane on eBay, and soon enough, everywhere else that prices based on eBay.
Some guy did this on the Wii, and made a video about the Maximum Games racing series. Now they're some of the most expensive collector's items you can find on the platform. Not that I want them, but this is how it all happens, in my estimation. So the tip here I guess, is to check for the worst selling games on any platform and see if you'd be interested in them before someone makes a video about them.
Fritz Chess is another fascination among Wii collectors, probably because someone simply made the claim that it was rare, and it now goes for insane prices. There are probably about 50 other games on Wii that sold about the same amount or less, and they can still be had dirt cheap, but everyone is scrambling to get Fritz Chess because legend of it's rarity is has become widespread. Why not a game like Geon Cube? That game sold roughly the same, and I'd much rather play that than a chess game. It think this only demonstrates how people just want something because someone said it's rare.
