Yeah... I'd mentioned on another forum that Gary and I were in a Pathfinder group that neither one of us could stand, not only because of all the house rules, but because the GM was deliberately slowing XP advancement to a crawl because apparently he wanted the game to be gritty. Which you just can't do if you're playing D&D/Pathfinder past a certain level because people have lots of hit points and healing. And I thought, "Why doesn't he just play HERO or GURPS or some other game where character advancement does not automatically translate into taking more damage?"
Basically some people are so attached to the D&D paradigm that they want to fit the peg into holes where it won't go. (Which explains, among other things, D20 Modern.)
Of course it's also been pointed out to me that converting a Pathfinder game to HERO basically means *creating* Pathfinder HERO almost out of whole cloth. But I think most of it other than the magic shouldn't be too hard.
