Basically, if you need 5 books to define your system (3 PHB, 2 DMGs) before you even get to the monsters, something ain't right.
I voted no - "don't care".
Basically, I am out of the target market for D&D. I'm an old fart with a young family - not much time. So if I am going to spend money on gaming instead of buying diapers for the kids, it better be something new and novel (not another way for a fighter to kill an orc). Basically, if you need 5 books to define your system (3 PHB, 2 DMGs) before you even get to the monsters, something ain't right. And given my situation, I do not have time to figure it out for them
I got plenty of D&D books if the pure D&D itch pops up. Otherwise, its Savage Worlds, Baby!!!
Well, that isn't really an accurate description, now is it? There was one PHB, one DMG, then one monster book. The other DMG and PHB books came later, not before, and they are supplemental, however much they call everything a core book.
