I think some of the buyer anger is when you have a history up to date of a sales range X game goes for, then you get a few people who will try and mark it another 10-20% higher and religiously just leave it up there, some may even have a ebay-offer option and not come down more than 1-5% off it firmly. The stuff can and will sit for months, but as with any hobby newbies pop up who don't think or research and they may just buy that copy. When that copy is bought precedent is made and others will see that and make a similar move against the prices copying the 'victor' of that high one while others will try another escalation. And the dog just keeps chasing the tail, biting it, feeling the pain, and then stupidly goes back to it again. The hate isn't totally justified on the behavior of the seller but also the tool who bought it at an overly high price helping to move the needle northward.

I'm still watching Ogre Battle for SNES and ever since that one jackass paid $110 for a loose cart on a BIN the new listings aren't still starting around $50~ but around $75-100 instead. The stuff thankfully isn't being purchased other than one copy in a lot of 8 other titles where the fair value of it all had the guy paying $80 on the game which is up from the $60~ sales rate of history. It will be interesting to see if this is the stupid moment, or it falls back to where it was. It's this kind of stuff I think is what gets the pissed off entitled sounding buyers because it just takes potentially one higher paid item by a fool to ruin it for everyone else.
