I would like to thank everyone who commented on my last post. I had over 250 hits, and quite a few comments. It seems that I touched a nerve.
First I would like to clarify a few things. I was referring mainly to D&D 4th Edition. Also, I'm not trying to make money. I DM my campaign at a small Independent Bookstore who I wish very much to keep open. It's becoming more apparent that D&D 4th Edition is not really a "Pen and Paper" game anymore. Applying '80s economics to this game is difficult. Now, I read the posts. I realize that you don't need all that stuff to play. Does it make it more fun, in my opinion, yes.
Here are some things that I've also decided. I won't allow illegally downloaded 4th Ed. PDF's at my table anymore. Also, before a campaign I will take a survey of my players. I'm going to let them decide what we'll do, and what they are willing to invest and we'll run with that. Again thanks for your comments.
