I like that roleplaying has one of the best cost to value ratios of any media hobby. It's such a good return on investment that my hobby's value is more often bottlenecked by the lack of time I have to read all the material I do get. At the top of my to-buy list is a one-book game (InSpectres, entirely due to the InSpectres in Spaaaace! play reports at lame mage) and a five-copy set of a generic rules system (Solar System); each are a mere US$20. That's an incredible price for how much play I hope to get out of them.
Alas, even such a low-cost hobby can give me pains in the wallet these days. That little "US" notation before the dollar sign is the latest part of the problem. It wasn't long ago that I could buy online from RPG retailers in the US nearly on-par, but the Canadian dollar is falling against the US dollar at a dismaying rate. (Aside, I don't really get that either. If the US economy is tanking, why do money traders still consider the US dollar "safe" and flock to it during economic crises?)
I've heard that the margins in RPG publishing can be pretty thin. Are we going to see games slip out of print because of gamers reining in their hobby spending in the face of the looming recession?
