With video games we basically have this thing where there's the potential to create your own world where you can do what you want and runs by whatever rules that you want and if it turns out your world is awesome and you're lucky you can get rich. The barriers to do all this are perceived to be quite low, and in some ways they actually are, at least in that a basic set of equipment, learning materials, and marketing ability can be acquired for very low cost. There is also actual game maker software that exists and is designed to provide a low barrier method of making games and there are libraries that programmers can purchase and use to implement various features.
Given a general desire to create, as well as at least partial knowledge of what is truly out there, and how TV and movies tell of god like powers that software has, I am not in the least bit surprised at beginners having these grand ambitions.
