Sure. All I'm saying is that when you are cutting back because buying power is down, D&D will be the decision to cut for some percentage of people who would otherwise have bought the books. It will also be the decision to buy over movies or concerts or something for some percentage of people who would otherwise have also done those other things.
I get that, but it could also be a decision that "Instead of bowling night, we're going to play a game." For some percentage, of course, it will be neither.
