None of these points are true in the gaming world so far. Projects are funded based on their ideas, but that does not necessarily entitle the public to a design by committee. Sure, people feel entitled to a voice, but ultimately it's the creators of the game that have the final say. I'm thinking major successes like Minecraft and Star Citizen. Minecraft was pretty much entirely driven by Notch, and Star Citizen is firmly in the hands of CIG.

Now, if they create something that people don't like, sure they will have a tough time getting funded again. But this is a point that is relevant to both the publisher and crowd sourcing model.
