Also, Wizards can change the terms of the license to whatever they want, whenever they want, and by using it you acknowledge that they have sole discretion to determine whether you've violated the agreement, and you forfeit the right to sue them, forfeit the right to a trial by jury over any related dispute, and using Open Game Content (which, again, they determine if you've done!) means that you implicitly agree to the terms of the license agreement. It's a frankly ridiculous document full of blatantly illegal shit that will never hold up in court and which no one in their right mind would agree to voluntarily. Wizards has tried to defend themselves saying that only the biggest companies will have to pay royalties - but they can change that any time to whatever they want!

It's literally the piece of paper from Parks and Rec that just says, "I can do what I want."
