Thos things are legal, too. I mean, WotC does own its intellectual property, and can set the terms on which it licenses others' use of that IP. I don't see any underhandedness.So what if Paizo took the d20 SRD and based an RPG on them? Anyone can do it, and it's legal, not underhanded. Underhanded is doing things like pulling pdf's of your products with little notice and killing an awesome character builder that people can actually own to force them to use an inferior web based program.
