$3/ month isn't that bad. And you really only need it if you want to use homebrew.
You know, this is an excellent question. If I purchase Curse of Strahd on DnDBeyond, what do I get for my money, beyond merely an electronic version of my book? Having all combats and maps preloaded into a combat tracker would be a LOT of saved effort, especially for those of us graceful and dignified (lazy) enough to run straight from the book, but the website does not yet have a combat tracker. What else, then?
Once again a stupid direction for PDF's for a company that is the current market leader, I want shares to fall for WotC so they become flexible,I have to purchase a D&D beyond account and/or purchase the PDF only usable on D&D Beyond's platform.
Please everyone don't buy the PDF's so Wotc will wake up?
Firstly, please learn how to use apostrophes. Secondly, they're not PDFs. It's a web app, with interactive and at-the-table functionality. You may or may not find it worthwhile, but calling it a PDF is to misrepresent it.
It is a way to sell PDF's through a app or site, it is hot garbage.
Unless I've missed something in all the announcements, DDB is not a VTT. Even with an initiative tracker and encounter builder (?) it will not work like ROll20 or Fantasy Grounds where you can have a map that all players can see, tokens to move on the maps, and virtual dice. I get that some people will find this useful, but those of us who have already invested in Roll20 or FG don't really get any benefit from this.
And if you aren't already using Roll20 or FG, consider that you can get what DDB offers and a VTT.
What those of us complaining really want, and would likely be willing to pay for even if we've already bought the books, is an official PDF version of the core books that is NOT locked to an online system, that is bookmarked, has links, and can be used on our PCs, or tablets or phones without a monthly fee or another company in the middle.
Offer me core book PDFs, FREE form online commitment, for $19.99 each, and I'll buy them. Until then I'll use the free version of DBB as a quick SRD, and probably nothing more.
