I too am very happy to see that it isn't plastered around. I want WotC to makes lots of money on material they are willing to sell to the public...
Other material, I don't care about.
Hmm. Well I bought it and our group tried it. The consensus was that magic that had been with D&D MUs since the beginning was toast and all classes were now "MUs". We decided to drop 4.0 except as something to play when we occasionally got burned out playing D&D.
I think it was because people started playing who actually grew up watching that show. They picked up the PHB and said, "Hey there are no real weapons here!"
The rest is history.
