A question... I couldn't find anywhere else on the web to post this. It's amazing how hard it is to find certain sorts of information. Mostly, this is legal information. =\ Anyway, as many of you are aware of, there are several games out there that use the AD&D or D&D 3rd Edition core rules, and other games that actually take place in Forgotten Realms. I'm planning on starting a small company between friends, producing great games. However, a few questions came up. If we used the core rules, just the rule engine (armor class, to-hit, etc), would that be illegal? And if so, how do I go about getting permission from whoever I have to get permission from? And who do I have to get permission from?
