I think there are three reasons we rarely see new ideas. First, it is hard for most people to think of new things to do. Second, on the rare occasion that someone DOES think of something new, it is unlikely that the person will have the great amount of determination that is required to make it. Thirdly, on the rare occasion that the first two things happen, the person will also have to learn how to host a server and keep players interested in it . These 3 troubles are what hold back new ideas from coming to life.
