Somewhat interestingly (to me at least) I find that i really don't care where players get their character building stuff. I mean, it is nice if they run it by me, but if we are playing 5E I don't care if players want to use a 2014, A5E, ToV or 2024 version of a class or whatever. It isn't like everything in the core book is properly balanced. Normally, though, I am running on Fantasy grounds and what player facing books I own on that platform are what choices they have access to.I don't really care where the DM gets their monster/challenges - that's their business.
My players using various sources, as DM, I certainly do care. I don't like letting players use any material I haven't vetted and rarely allow other's homebrew - the balance/lore on a lot is usually out of my comfort zone.
Yes, because I know many 3PP creatures and such are not well-balanced to the game IME.If so, why?
ThisHelps maintain the D&Dishness of D&D.
If it turns out that I don't like what they do, then I can choose not to play.
Just an idle curiosity.
If you are playing D&D (any edition, but 3e on have more options in this regard), do you care about where your DM is getting their monsters and stuff? in other words, do you expect or desire your DM to use official monsters? Do you have concerns if they are using 3rd party monster books? Homebrewing monsters? Does it matter if they are using Grimtooth's traps or similar?
If so, why?
If not, is that universal or are there sources that would worry you?
Thanks.
