New Game Projects

I just really want to cosign the the danger of the sunk cost fallacy and how hard it is, i've seen it be, for organizations to kill games. I'm a very strong believer in prototypes. A first game i ever produced was because of a prototype i made in a week end. But i think you need a really strict criteria about how long a team gets to prove that a prototype is worth building or being killed. So just the number of people on these new game projects that are inevitably exhausting should be a low percentagea.
