Do they? People investing money through crowdfunding are just that, investors. If you invest 50$ and get 50 hours of game play, then the investment was good, independently of whether the game was released or not. If you invest 20.000$ and no game is ever released, and you don't get a % of the sales, then it was probably a bad investment.

Being a bad investor is not an illness. Just because we don't die easily anymore does not mean that our environment isn't hostile, that natural selection does not exist.

Some people want to have fulfilling lives that make the world a better place and become doctors, and nurses, and teachers, and cops, and firefighters, ... and work long hours, with little holiday, for little pay.

Others want to enjoy their every moment on earth, learn to exploit their environment for profit, and this is how it looks like nowadays. There are always people that are smarter than you, and there are always people that aren't.

Crowdfunding is great because it gives you access to thousands of non-professional investors that have too much money and don't know what they are doing. People who want a game go and buy a game, but these people made an investment. If that's bad, it is IMO their own fault.
