the $5 has to be from somewhere it can not be fake, any fake money made is illgeal. This is how Epic got in trouble for such thing, Valve only has that money because they are rich to do so, not much answers can be given.
cheap games like my are cheap because of the time and resorce i spent on it. other games that were build in years or even longer have to earn the money back. it is not simple thing to spent money and offer it for cheap. anytime that happens people will think the game is cheap, just how many iphones, cars, gaming computers and food are consider better because of money not because of cheap.
