NextGen RPG welcomes all game genres and systems.  We want our players and GMs to be enthusiastic about their games, so as long as it appeals to them, it works for us.  Our emphasis here is on original fiction and concepts, so most fan related games that are based on television shows, movies, and other existing media would not be a good fit for the site.  This isn't meant to exclude anyone or diminish the value of those games, only that it diverges from the original fiction aspect that we're striving for here.
