Now im reminded of the guys I met at a student association party (for a student association which had an active boardgaming club) who didn't want to tell me about the boardgame they were developing because I needed to sign an NDA first, and they had no papers with them, and they wanted to see if they could patent the ideas. Such a weird moment to be introduced to people because they are actively trying to develop a board game, and I also liked board games for them to go 'its all a secret'. Can't recall if I laughed in their faces (as well, from what I heard from reading about board game development, NDAs like this were unheard of, same with patents, and nobody is going to steal your idea (and you will not make much money on it)). I didn't even get the genre. (And like I would steal their ideas, I have my own unfinished ideas thank you very much).
