A. Getting into any hobby will have an up-front investment cost. Yes, that sucks, but it’s still true that RPGs are on the more affordable side.
B. Obviously, and that’s part of what keeps RPGs such an economical hobby.
C. Which looks like a lot, but again, compare that to the initial investment in basically any other hobby and it starts to look more reasonable, especially for how many entertainment hours you get out of that investment.
Like, I’m not saying it isn’t expensive. I’m saying all entertainment is expensive, and as entertainment expenses go, RPGs get you a lot of bang for your buck.
