In addition to grading games just being dumb in general, WATA has also graded Pokemon ROM hacks that someone put on real carts, and printed up fake boxes for. People are trying to sell those for hundreds to thousands now.
oh great, rom hacks are being sold for higher prices now.
oh you mean people are trying to sell it. that means it's going to fail miserably and people are forced to adjust the price of the thing they're selling to something more accessible! read: lower prices. many favor lower prices.
US$5 is acceptable for selling your physical copy of the game or console you accuse emudevs of "ruining" btw. just in case you sellers/collectors are reading this thread. you both are quite the same actually.
