As stated by Epsy....except for the naive collectable book game part. The open game license has opened opportunities for people to express and spread their ideas among the gaming industry... that's all. Nobody is making you buy these books. They are simply made so that, people will have a much wider variety of ideas floating through their heads. Who knew that letting age-old campaign settings expand and creating new monsters for groups that have memorized monster stats (and the DM is too ignorant to change them) is a bad thing. If you truly think that the game is turning terrible because, for some reason, more books stop your flow of creative thinking then teach new 'naive' players 2nd or 1st edition rules.
Example? This is a rant. But gaming rules!
