Have you used these big setting books? Have you gotten your money's worth? It is up to everyone to decide if they got their money's worth I guess. Some may read them and never use them in a campaign and still think they got it, while others may think if they did not get three campaigns it was not worth it. Just wondering, thanks
It varies.
I got a lot of Lost Lands stuff in bundles and on big sales, but I have not gone through a lot of the setting stuff as of yet. Mostly a bunch of the Blight and some of Bard's Gate is stuff I have gone through. I would love to run the
Northlands Saga though.
Ptolus I read a bunch, I am really glad I got the free player's guide and I am happy I got the Bundle of Holding for the 5e version. I was also satisfied I got my money's worth for me when I bought the big d20 version when it was on a mega sale. It is a big part of my homebrew mashup setting.
Golarion I have used a ton, it is also a big part of my mashup setting with a Ptolus Holy Lothian Empire overlay. I read the 3.5 setting hardcover all the way through. I have run multiple Golarion adventure paths in my homebrew setting.
Freeport I read the pirate's guide cover to cover and ran multiple campaigns in the city and it is part of my mashup setting as well. Very happy with that.
Hamunaptra I have a fantasy Egypt in my setting with elements that have come up in game. It is a bit of a fusion of Golarion's Osirion, Hamunaptra, Lost Lands Necropolis, Mystara Nithia, Ravenloft Har Akir, and FR Mulhorand. I have sourcebooks with stuff from each and more Egyptian stuff to pull from including the Mummy's Mask AP.
There is a lot of stuff I have gotten but have not read yet, but it is there as a reference if my games go that direction or for me to read in the future. A number of lost lands stuff is like that.
I don't have a lot of buyer's remorse, I mostly get PDFs, stay within my hobby/gaming budget, and buy things that interest me that are on sales.
