OGL and GSL
None of this would have happened if Wotc wasnt late on the GSL and had it so draconian.
Pathfinder RPG would NOT have come out in 3.5....as its not needed. Its ONLY needed to support paizo's AP's and Adventures....since there is no longer a "core ruleset" for 3.5 in print. Pathfinder RPG isnt needed in 3.5, but it is in 4e.
OGL isnt really the problem. Wotc's handling of the transition to a new license was.
The truth is that if they hadn't removed dragon and dungeon from Paizo they might still have sorted out the mess their pr and whoever decided 4e was essential and that the 3e crowd was so much loose change.
Had they kept Paizo in the loop and not played petty tyrant there might not have even been any sign of Pathfinder instead rather than Paizo biting the hand that reared it, its more like WOTC decided to abandon the kitten only to find the kittern was now more of a tiger than some backstreet wildcat with no interest in what their former owner was doing.
Sorry hope that was clear enough.
Now had WOTC had had someone with some idea of what they were doing, it might have gone entirely different at the moment the only way I can see them getting themselves out of the barbeque they're cooking themselves in is either getting Hasbro to buy out Paizo or seriously think of a way to make amends perhaps even produce some webisodes to highlight 4e you know sort of an internet version of d&d the series for the 21st century sort of thing...
I mean come on, after those little strange introductions of the tiefling, gnome, beholder and mind flayer wouldn't you want to see something concrete to make you say, how did they do that?
They claim to be trying to encourage a new generation of kids to play d&d, yet aren't too interested in getting the existing crowd to help... well WOTC ask Gamer Zero why people are watching his youtube videos, you have an audience and you aren't treating them properly, get someone Keith Baker, James Wyatt better yet Ed Greenwood write up a multiple episode webisode series you can host on the d&d website introduce the new cast of 4e and what they can do make it halfway decent (ie better than those other ones) and you'll find more interest.
The GSL might then not be as important to the other companies if people want to play 4e.
At present I'm only playing and I prefer 3.0, Eberron got me to buy 3.5 and if it wasn't for dragon and dungeon that might not have even made me buy 3.0. Your internet replacement isn't up to scratch, best of luck then.
