Pathfinder, being the Paizo-operation extension of the 3.5 rules after WotC continued to D&D 4th edition, seems like it should fit, but I wanted to verify before I went around posting anything.
My friends as I don't always play dungeon fantasy, but when we do, we prefer Pathfinder.
Stay murder-hobos, my friends.
It would be silly to exclude it anyway. PF had been the most sold D&D variant during the 4e era, is at least still tied with 5e in popularity and sales, and a lot of PF groups use material from 3.5 that hasn't found its way into PF like IP-protected monsters (beholders, mind flayers...) and unconverted classes (Warlock, Tome of Battle, Spellthief...)
Yes, I agree. It was more a question of how focused you wanted to make it. If I had bothered to read the sidebar, I would've noticed you mirror my thoughts on the matter, in that let's just keep fans of the general "dungeon fantasy ttrpg" genre together.
Now we just need a general tabletop gaming sub so I can talk about GURPS, my all-time favorite system. :)
PF content is absolutely welcome. It is mentioned in the sidebar, after all :)
