I remember having a demo for a game which was struggling and not very popular in my area. I went well until I mentioned I wanted to find some more players and make a regular group because the game looked fun. This immediately enraged the guy to the point where he made a very good impression of a furious guard dog trying to break off his leash and bite my face off, with the subtext of "how dare you say that you, a random person, could succeed in building a community where *I* have failed despite years of trying!?" Curiously enough, something like a year or two later a community did emerge from completely unrelated people. Gee, I wonder how they could succeed where he failed.
