Why? Because some people who usually get psyched about a D&D products were chosen to test this one and, surprise, they were psyched about PoA?
They weren't as psyched for Tyranny.
What's the alternative? Dismissing the idea a good product could be released and being pessimistic about the release schedule? Meh, pass. I have no problems ripping WotC a new one if they deserve it, but I'm not going to expect a product to fail without reason.
PDFs don't count. Setting books don't count. What, precisely, counts as support? Rule expansions? If that is true, 1E had next to no support at all until 1985. Adventures? In that case, 5E has next to no support now.
PDFs apparently don't count as support from WotC. And PDF setting content doesn't either. So if WotC can't count the stuff they're putting up online, why should other companies?
This is part of my point: 1e had very little "support" as we would now recognise it. Two extra monster books, two PC splatbooks, and four DM sourcebooks. 3e and 4e had that after a year. And while 1e started releasing waves of adventures, that took time to build up.
I think you are wrong and you can see many discussion around the Forgotten Realms for evidence. People are clamoring for setting material and consider it to be support. I can't quite grok why you have such a narrow definition of "support."
Well, WotC just released
Ed Greenwood Presents the Forgotten Realms during the playtest process. Did that count as support?
And a search of "Forgotten Realms" on DnDClassics.com turns up a result of 108 items. Three times most other settings (although only 2x Ravenloft and Greyhawk).
What a strange thing to assert. Paizo has been a successful company for
over a decade now and the Pathfinder RPG has been going strong and growing for almost 6 years (not counting the Beta period). There is some concern on their boards about rules bloat, but otherwise it is a well loved game with lots of support, in adventures, setting material and rules. If D&D was going to emulate any RPG out there from a publishing standpoint, I can't think of a better one.
Paizo struggled for a LOT of that decade. They had repeated financial troubles and were operating hand-to-mouth for half of that period. They didn't expect Pathfinder to be the success it was and were unprepared, so they almost lucked into their fortune. Not the best company to emulate.
Now, I really like Paizo. I like the team there a LOT and I have nothing but respect and good things to say about them. But one of the positive things I used to say was that they were being restrained in terms of content and releases, with three hardcovers a year, few extra classes and the like. They've really started to move against the game and business model that helped them establish themselves.
Well Lost Mines was quite good. I am really paying attention to authors now running a 5E adventure by Skip Williams on Thursday.
What annoyed my about HoTDQ was that it should not have seen print in the condition it was in IMHO. Its only the size of a single Paizo monthly AP and it sucked. Thing is I am a fan of Wolfgang Baur as he used to submit to Dungeon magazine back in the AD&D days and he wrote part 1 of The Age of Worms AP.
We are not that far short of a year in and there is no Rise of the Runelords type adventure for 5E. Paizo got there 1st AP right post Dungeon, beats me why WoTC could not do it when LMoP was decent. Individually most of the Paizo APs are good, read enough of them they become a bit formulaic.
A Pathfinder AP is about 90-odd pages, but only 60 of that is adventure. Yes, the Pathfinder APs are 360 pages of adventure compared to Tyranny's 196, but that has to do with speed of play. Pathfinder PCs level slower than 3e PCs. WotC spent the last two editions speeding up levelling. Pathfinder APs have a LOT of filler encounters.
But that said, I did find Tyranny on the short side as well. Especially for the price. I'm thankful
Princes of the Apocalypse is a single volume and thus far cheaper.
That said, Paizo's first couple APs (Shackled City and Age of Worms) were a learning experience and had problems. They started Shackled City back in 2003, so they had 3.5 years of AP experience (and 3 APs) before they tackled Rise of the Runelords. Why should WotC get it right the first time? (Yeah, they did Scales of War too early in 4e, but the staff in charge of that was likely very different.)
And Paizo wan't designing an edition at the same time. Heck, the first AP for the Pathfinder RPG was Council of Thieves, which wasn't well received. And they weren't working out the bugs of working with licence partners.
