He did generalized it, he mentioned the people who only buy core. Being someone who stopped buying anything but core with 3e, because of the overwhelming amount of crap, I think it is safe to apply in a general way; albeit only in a minor way.
Either way, its all conjecture and hope anyways. As an old coach of mine would say: “If ‘ifs’ and ‘buts’ were candy and nuts we’d all have a merry f’n christmas”. I think that applies to GSL/OGL/WotC/D&D a lot. I also think it will be what people make of it for themselves.
On a side note, maybe I’m missing something b/c the last D&D book I bought (prior to 4e) was 3.5 core set, but why all the love for Piazo? Not a challenge, I honestly don’t know. I have a real hard time trusting TPP after a lot the one’s I liked died with 3.5 or started producing crap.
The letter of the day is “C”. “C” is for crap.
