I don't know man.
I remember that there were SOME people who were opposed to the change. But, then again, this was the days when there were people driving around with bumper stickers which said "Save D&D, kill a Magic Player". D&D was hurting bad.
Around here I had to leave work early to go buy my copy on release day before they were gone. Yes, thats an anecdote, but the chatter online everywhere was huge.
2000 was a really good year for gaming.
I don't know how I can persuade you otherwise, but you may as well be telling me the sun comes up in the west.
I'll just accept that this is your memory of it.
PF2E is at 9 months now. How many 3PP titles do you think we could find that were published in the first 9 months after August 2000?
Edit: I do think a lot of people really just didn't like the crunch heavy approach. It was a big change from prior editions. (I hear feats and powers was along the lines, but I can't speak to that phase myself). It is completely fair to just not like it with a completely lack of "fear".
