The pie analogy doesn't quite work, because it leaves out the issue of player acquisition - something traditionally done by the leading RPG in the industry. D&D is the only mainstream brand the industry has of its own (no matter what the difference in sales between the leading games are), and WotC is in a position to leverage that to grow the industry in ways that other companies can't, although Paizo has made some inroads into that with its Beginner Box and various branding initiatives like comic books, toys, and so on. So a successful D&D means a bigger RPG industry with more players in it.
Plus, of course, actual competition makes people bring their A-Game. Neither company can coast. This benefits everybody!
I think that the size of the D&D team relative to Pathfinder's is sad only if you think that wotc should follow the same in-house development strategy as Paizo.But Hasbro is giving them less staff to work with than Paizo can scrape together? That's just sad. (snip)
Pathfinder, despite it's success, isn't D&D. D&D simply has a lot more name recognition and brand appeal. Paizo never did a good job at expanding their brand outside of the pen and paper market, but then 'Pathfinder' isn't the most appealing name either.
I know when it was announced, the first thought was they named it after a Ranger prestige class or feat and why in hell would they do that. It's probably why the only Pathfinder videogame we will ever see is created by a company operated by Paizo and funded by a Kickstarter.
Between the poor branding and the perception that Pathfinder is just a 3rd party off-shoot of D&D 3.5e, I can't imagine it does that well in the 5e era.
You do realize that Pathfinder is 5 years old, and D&D is 40, right?
You also realize that D&D didn't have it's first video game until it was 14 years old, right?
Seems like you just don't like Paizo/Pathfinder - which is fine, but don't compare apples and oranges and say oranges failed because they're not apples (and orange is a stupid color).
So I suspect the post-5th edition world is:
-D&D does well in the 3rd and maybe 4th quarter of 2014
-Pathfinder retakes the number 1 spot in 4th quarter 2014 or 1st quarter 2015
-The D&D playerbase is predominantly the portion of 4th edition that was "Moderate" in commitment to it.
-The 4th edition hardcore and the pre-4th edition players largely stay where they are.
-In 2nd to 3rd quarter 2015 WOTC announces a major change in direction: Going edition neutral or announces that they're releasing "3.75" an update to the 3.5 ruleset to correct its issues and meant to make it usable with 5th edition product like the Monster Manual (Likely while porting over a few of 5th edition's features), possibly the same with 4th edition.
I think the wotc staff has made it excruciatingly clear with both words and actions that messageboard forums are not representative of the market. Whether you want to believe them is another matter, of course.If you look around, it seems that 5th edition's customer base is 4th edition's customer base. The poll at the top of the forum shows ~70% "Current players", which I believe represents 4th edition players. Many of the topics are 4th edition oriented, especially on WOTC's forums. On WOTC's forums there's virtually no indication of pre-4th edition players returning, and an overwhelming trend towards 4th edition oriented takes/discussion.
If these areas represent the edition's customer base as a whole, then 5th edition isn't doing much more than continuing to sell to the 4th edition market. (snip)
