I'm claiming that any game that was made because someone played D&D and found something missing in D&D that they wanted in their D&D so they made their own ruleset in response to D&D is a 'fantasy heartbreaker'.You're basically defining the entire OSR, however innovative, as fantasy heartbreakers. And no, no they aren't. And neither is Daggerheart.

Now, as I mentioned right above... I also acknowledge that some people find the term 'fantasy heartbreaker' dismissive, which is why they will argue that certain games are not. Because otherwise it is tantamount to admitting this other game is "lesser" than D&D. That's fine! I have no problem with someone taking that side of the argument. I acknowledge their feelings, even if I don't hold them myself. Which just means we end up at an impasse-- I call something a 'fantasy heartbreaker' and someone else doesn't. Whatever. So be it.
