Thus isn't a thread about "wow, look at how high some games can sell for, no game is worth more than $20". This is about specific items that regularly sell relatively cheap being advertised for outrageous prices, compared to what they can actually be currently found for. It is also about exposing clear market manipulation. The story of how this thread even came to be sums it up pretty ironically.
Dynastic Hero is or was easy to find for $5. The only reason it doesn't come up as often now is that it's not worth the effort for a seller because it's so worthless. But we still see the odd seller asking hundreds of dollars for the same extremely common version. If a collector wants something so bad yet somehow knows absolutely nothing about it, that they would pay one hundred times the going rate for it, sure that's "their business". But what is so unreasonable about discussing how unreasonable it is to monetarily value things so much which some people clearly don't care enough about to actually learn anything about?
Many of the more vocal anti-gougers in this thread happily spend $100+ on single games. They just don't take pride in spending 200% - 1000% on any given game. Real collectors collect things they genuinely admire. The current wave of nu-collectors, who consider it a "hobby", who value items based on what they believe others value them for and consider collectibles an "investment", are really the opposite of what traditional collectors are and they really should come up with new terms to describe themselves and their investment schemes.
