Et tu, Brute?
Not particularly. I play 3.5e, but that's mostly because it's a) common and b) decent once it's been fixed up; it's still got a boatload of problems, which is part of why I'm cautiously optimistic about 5e.
If you want more meaningless facts, instead of anecdotal evidence, how about the industry report from Roll20?
The reason Tack's numbers were meaningless has already been mentioned, and you ignored that post. I'll quote it here to see if you ignore it again.
Also @ Sales figures, 3.5e stopped being published in 2008, so keep that in mind. Basically, those numbers are saying that Pathfinder did beter than 4e.
Arguing that PF sales in those quarters make PF more played and more popular than 3.5e is like arguing that Kick Ass 2 is more popular than Star Wars: A New Hope because the former sold more tickets at the box office in 2013.
Likewise, as mentioned above, 3.5e was more popular with players even in the data you cherrypicked from a single source.
Furthermore, that source is questionable. Their sample size is a scant 2,500 people from a self-selected group (people from the roll20 community who opted into the survey, taken over a couple months from a single year). That's from an estimated playerbase of
20 million people over the course of its history, with an estimated
six million players as of 2007.
Additionally,
compiled google search data indicates that it took nearly six years after the release of Pathfinder for it to pass 3.5e in general search volume, and that it didn't even start gaining until 3.5e went out of print and 4e was released, indicating that a good chunk of the playerbase for it were 3.5e players who were disappointed by 4e and unwilling to stick with a game which was no longer in print.
Likewise, the data also shows that the popularity of 3.5e has been holding steady since 2009, despite being out of print and in competition with both PF and 4e. Even more telling, however, is the fact that
specific searches per month for character sheets, character generators, and PDFs for D&D vs. PF are overwhelmingly in favor of D&D; even if you strip half the numbers from D&D to account for non-3.5e searches (more than fair, given that 3.5e is still by far the most popular edition at the time of this study), 3.5e still beats out PF in each of those categories, which I would argue are more relevant as they are directly associated with actively playing the game rather than looking for any sort of information related to it.
