Ooh, careful there.... I don't think the numbers support you there.
You agree with me on smartphones. But, check it out - in the US, 56% of adults have smartphones.
But, according to Morrus' "
Hot Games" page, which takes a pretty broad sampling,
less than 5% of D&D discussion is about the OSR and those old games.
Sure, WotC reissued the old core books. But I think that was to fuel nostalgia, and to show the range of thought in the company. I don't think there's call to say there are enough OSR folks themselves to have made them a real business driver.
If we look at cell phones, and say, at 56% penetration, that really, the new tech is in, and the old tech is out, when we look at OSR, which is quite clearly way, way down the list of games people are playing, should we not say the same thing?
