But for all intents and purposes, isn't WoTC "the industry"?
Not saying that other companies don't exist or that they're #1 in the miniatures business but the gap between them and their second competitor is well, all of their competitors probably don't do as much business RPG wise and probably CCG wise no?
I really cant say I can trust myself making a guess here and this is a pretty significant one. I am not sure: there are a number of companies that each month make a considerable amount of new product for their fanbases.
