Did you find any case at all regarding RPGs specifically?
Also, would you (and other lawyers in the thread) recommend any casebook / book / resources regarding game law? I am a foreign lawyer with much interest in studying aspects of gaming (tabletop, videogames etc.) related to the law. Thx :)
On copyright of RPG classes, wouldn't protecting these general classes amount to a restriction on the use of a straightforward concept and thus restrict creativity, countering the purpose of copyright? There aren't many ways to effectively express that a character is a fighter or a monk etc.
