Daggerheart is not at all a PbtA game, though it borrows elements. It borrows pretty heftily from a lot of predecessors besides 5e, like pbta, fitd, cypher/numenera, and SWRPG/Genesys. With imo the last one sharing the most DNA.

God, why is the games industry so fucking illiterate when it comes to IP law. File a trademark opposition? They’re suing! File a patent application without issued claims or even substantive examination? They’ve patented it! These aren’t crazy fucking complicated concepts, but the journalism for games industries like actively stunts the understanding of these things by the market.
