[QUOTE="Griffith Dragonlake, post: 3805937, member: 40379"] I Am Not A Lawyer. A careful reading of the d20 license and the Open Gaming License indicates that all d20 content is Open Gaming Content (OGC) whereas all OGC is not d20. The d20 or not d20 is simply whether or not you choose to use the d20 logo and/or declare compatablity with D&D. Doing so restricts you from a small number of functions, e.g. describing how to assign ability scores. You can state that characters have a specific point buy, but you cannot state how to assign those points. All in all, there's very little in the d20 license that you cannot do. New magic system? d20. No skills or feats? d20. Use playing cards to resolve combat instead of rolling a d20? d20. Changing the definition of what "dazed" means? OGL, not d20. In answer to you questions: 1. All work based on the SRD must come with an updated Open Gaming License regardless of whether or not you choose to indicate D&D compatibility. 2. You retain copyright to all content you create. Fluff may be declared as product identity which means that others must get your permission. Gaming mechanics cannot be declared as product identity. Not that claiming generic flufff as PI is considered bad form (I'm looking at you Monte Cook). For example, "magic arrow" could be declared PI but violates the spirit. "Bob's Magic Arrow" is the intent of PI. 3. There is no problem with modifying OGC and releasing it under the terms of the OGL. The only reason to base it off of existing OGC and use the OGL is because the heavy lifting of game engine design has been done for you. If you intend to design an entire game from the ground up, there's no benefit from using the OGL. If you wish to indicate D&D compatibility, then you must follow the OGL and the d20 license. [/QUOTE]
