I mean, the Sagamore Ballroom was divided this year (with a third of it going to 40K lasertag). So what you're seeing is a fraction of the interest from GenCons at least 5 years ago.
The lines at the Paizo booth used to stretch out of the Vendor Hall, and now the shopping line would evaporate within an hour of the floor's opening each morning. It was disheartening to see stacks of Dark Archive sitting there on Sunday after seeing Free League and Zweihander selling out of entire product ranges. [And yes, I know smaller companies bring fewer copies and might sell out quicker, but presumably they also have less promotion, less interest, fewer fans, etc - so it should be comparable.]
I'm not bringing this up to disparage Paizo, Pathfinder 2, or its many fans. As I've started numerous times, I like the system overall. But I think that when people say "it's going as strong as ever" and then I see the event space one-third the size of the last time I went - that tells me that "in practice" there are some issues.
As fans, should we promote it more? Do they need more PFS GMs at events?
