And nowhere did I say or even imply that it did.
My point was that 5E is almost certainly drawing its sales from audiences beyond the Pathfinder fans.
Of course it is. But that flies in the face of the narrative that 5E is engaged in an evenly-matched death struggle with Pathfinder.
For almost two years, here, and on other forums, we've been continually reassured that 5E will be a "bust" because it's going to further divide a dwindling tabletop RPG market. The notion was that even if it could "recapture" half of the fans it lost to Pathfinder, it would lose just as many or more fans of 4E, and the net result would be diminished sales.
Yet, here we are, with the 5E PHB a week into its official release and, by all indications, it's a smash sales success, placing not only in Amazon's top ten in new releases, but the number one spot among all books (at least temporarily.)
It's safe to say there a lot of gamers who hope 5E fails. Or that it at least proves less popular than Pathfinder or 4E. They'll interpret any sales data in the worst possible light, and continue doing so.
No Pathfinder product has ever achieved that. No D&D product has ever achieved that. And what this suggests is that the audience buying these books isn't restricted to current players of 4E or Pathfinder.
What it suggests is that the lapsed gamer market is much larger than anyone realized and that WotC has successfully tapped into a significant portion of it.
I'm pretty sure WotC realized how big the lapsed gamer market is. Everything about the design and marketing of 5E speaks to that. The people who didn't realize how big it was are the folks who hang out on forums and are deeply invested in a particular edition of the game. They make the mistake of conflating the thousands of people who are active on RPG forums with the hundreds of thousands - even millions - who play or have an interest in D&D.
