After spending the last 105 minutes reading the entire postings, I find that I concur with the overall sentiment: We love well-written stories, clever adventures, and pretty pictures. It's what captivated us when we started, and it's what keeps us coming back for more.
I started gaming in 1979 and changed with all the editions; however, my group will not invest in the new 4th edition. Sure, I might purchase 4.0 products - adventures, scenarios, and accessories, but no rule books. My group and I are more than a little disillusioned with the "upgrades," and we already throw out the rules of 3.5 that we don't like, so why invest in more of the same?
So, here it is: It doesn't really matter if PAIZO updates to the new edition, stay where they are, or create something new. Because as long as you continue to sell a QUALITY product, and advertise it, then you will always have a niche in this market.
Gamers are fans; not just of the game, but also of the designers, writers, and artists who create and improve our hobby. As long as the product is good, we will follow and incorporate your creations to best suit our individual needs, regardless if that is 4.0,, 3.5, or something new altogether.
To quote Shakespeare, "The play's the thing."
Best wishes on your continued success!
