I've expressed my feelings on 4th edition here before. I'm not such a grognard that I hate what they've done. I understand the need for a product like D&D to adapt to a new generation if it is going to thrive.
There is much banter that 4th edition isn't doing that well, and much complaining. I'm glad my friend Joseph Goodman has cleared up the myths:
"My opinion on D&D 4E"
In case you don't want to read his longish post, the short of it is: yes, it is doing very well. And for that I am glad. As for me and my gaming group, we're having a blast playing S&W, and having fun with friends is what it's all about.
