One of my pet peeves about #ttrpg fandom is when people say:

"This RPG product is too expensive!"

No. The RPG industry has tiny, tiny margins, and only a minuscule portion of RPG authors are able to make a living from this - and only barely so, at that. In that context, I find the notion that they are somehow "price-gouging" to be borderline offensive.

Saying:

"I cannot afford this!"

or

"I cannot justify the expense!"

is entirely fine, however - what an RPG product is really worth to a reader is very subjective, after all.
