I'd like an entire game focused on it, but as trends go, I could see it being the new zombie mode. I genuinely think it's something people would buy into and continue to do after a week in when nerds hack the source code and realize it's genuinely a hopeless effort. It still gives a similar gameplay experience to any other fps, friendly fire would always be on so people will eventually pvp. If people want games to be art, we should have Dadaist games
