Gee, a strawman; I don't recall anyone saying "seriously eclipsed". And mind you by the same standards you're putting forward, you don't have the evidence that D&D has ever beat Pathfinder in sales.
The predominance of evidence is that Pathfinder is beating D&D in book sales. Our evidence is weak, but all the evidence we have points in the same direction; it supports a tentative conclusion. If I had one bit of evidence that the naysayers really believed it was possible that D&D was actually 3rd in the list, or that the data was previously wrong and that Pathfinder has been leading for a while, then I'd be more accepting; but the counter-argument seems to presume that in absence of evidence, we must accept that D&D 4 is number one.
Strawman? Nope. Looking back at my post, I should have left out the word "seriously" as the you (and others) are simply claiming greater Pathfinder sales, not necessarily "seriously" greater sales. But the way folks present their conclusions . . . Your saying that there is a "predominance" of evidence, but that the evidence is weak, heh, that makes me giggle a bit. There is evidence, it isn't predominant, and it is weak.
I'm not saying that Pathfinder ISN'T outselling D&D or that D&D is outselling Pathfinder . . . I'm saying we don't have worthwhile evidence either way. I do believe that Pathfinder is selling quite well, Paizo is an amazing company that puts out amazing stuff and there is no doubt they've been very successful because of it. And D&D has certainly taken a beating over the past couple of years, and if any game has a chance of overtaking it, even if only momentarily, it's Pathfinder. But again, the existing evidence is weak, and ignores major aspects of both companies sales strategies.
If both Paizo and WotC released their sales figures tomorrow, so we could do a worthwhile comparison to see who's doing better . . . I'd still shrug and say, "So what?" The two games remain good games with healthy sales. Which one is on top matters not to me. The only exception might be if WotC sales are seriously slumping and endangering the brand (which is inferred by some on the "Paizo's winning" side), that would concern me.
The counter-argument is, more accurately, that we know quite well that D&D has been the best-selling tabletop RPG on the market for most (if not all) of the last decade, and that only recently has a game risen to possibly challenge it. The counter-argument then posits that, in the absence of evidence to the contrary, we must continue to operate under the assumption that things are as they have been for the last decade.
Now, this says nothing about what happens if we do come across credible evidence, but I think a lot of people are making the argument that what he have in terms of evidence does not amount to what is sufficient to change our assumptions.
I can't give you any more XP, but not only do we agree but your use your words better than I do! And you're right, D&D is THE original RPG that has been in continuous publication since 1974 (well, with that slight end-of-TSR blip) and that all subsequent RPG games are derived from. Ask the average non-gamer to name five RPG games and they'll be able to answer, "D&D and, um, D&D four more times?" D&D gets the benefit of the doubt when doing these usually meaningless sales comparisons because it's the king baby, and denying that is just plain silly. Doesn't mean it has to be your favorite game, or that it is even the "best" game, but it is the King of RPG Games. Also doesn't mean it can't be eclipsed in sales, as it was in the 90s by the World of Darkness games, and as it
may be today by Pathfinder. But in five years, ten years, or thirty years down the road, my money is on D&D remaining the King of RPG Games, not Pathfinder or any other game.
But, I won't be convincing anyone who's deadset in believing that there is enough evidence to show Pathfinder is king-for-a-day in sales, or that it really matters all that much. And they won't be convincing me either . . . and I keep promising myself to stay out of these types of never-ending arguments . . . so I'm done . . . promise!
