Hence why I added the descriptor of 'business'.
As can be seen with the ongoing discussion, calling something a 'golden age' just because its what one person has an emotional attachment to is pretty useless in a generic discussion. Or at least limited when trying to reach agreement between differing people or when trying to be objective. (And a purely subjective opinions only useful for others with the same view, and since they already have the same view, don't need to hear it from another.)
Yea, part of what would make a decision to publish 3.X material a terrible business idea. Even Paizo had to come out with another edition just so they could sell something.
