It's not the forge, it's the forgies.
The games themselves are really not problematic, although some of them suck. If you want to pay $20 for a pamphlet, some cardboard cutouts and a plastic bug, that's your business. I have my own nonsense that I like, so that's fine.
It's the people.
The problem is that you have a group of ordinary, mundane people who are trying to convince the world (and each other) that they are actually smart, vibrant, interesting people, and that they deserve money and respect from their crackpot ideas and gaming failures. The way they all periodically (and obsessively) validate each other in a frantic podcast and link fest is sort of like a little glimpse into the insecurity hatch.
