One of the reasons we know the division of the audience hurt TSR was because someone at WotC sat down and did the numbers and research and looked at the sales figures and found that people weren't buying multiple lines. Or they'd buy bits of two but nothing from others.I hear what you are saying. OTOH I think a lot of people DID buy material for more than one setting, and you do broaden your offerings. There are people that might not buy WoG no matter what, but they might buy DS. Obviously there's a point where one product is just cannibalizing others, but its not clear exactly where that point is. Its a matter of doing the market research, and I think we can conclude that TSR in the 90's was not really doing that very well.
And there'd be people that bought no setting books and just generic products.
WotC most recent attempt was a little different in that it gave each setting very minimal support beyond an updated book, so it would be harder for the division to really hurt the game. At worst they would have one or two books that didn't sell as well.We can look at recent WotC and see that multiple settings can be worthwhile, 4e has FR, DS, and Eberron, which are all pretty distinct and one would presume they determined that it was worth providing some support to each one, with 'PoL' providing a fairly generic default. One could question whether FR and PoL were really significantly different, but I think WotC clearly felt that a 'classic' setting was a necessity. Clearly they also weren't interested in large overlap which might have existed with say also republishing WoG or even DL. It seems to me the lesson is you need to do your homework, but there's room in a large product line for 3-4 settings.
But it should be noted that after the first couple years, they swapped from a DM book and Player book to a single large DM/player book for Dark Sun and Neverwinter. Possibly because they hoped making half the book mechanics that could be used in almost any setting might help sales. And they very quickly returned to the Forgotten Realms.
We don't know how well Eberron and Dark Sun did, especially compared to generic books. So it's unfounded to say there's room for 3-4 settings.
Plus, WotC has the advantage of their settings having an established audience and much of the work writing and designing the settings having already been done. The 4e books had fans waiting for the products and willing to buy because they'd been waiting for more Dark Sun for years, while the writers just had to compile information from past books. This is very different than having to make a brand new setting that takes time and does not have a built in audience, like Paizo would need to have.
There's also numerous 3rd Party Publishers making campaign settings and worlds. So anyone who doesn't want Golarion isn't lacking for options, either PF specific or old 3e worlds.
