These new requirements are laid out in a blog post called "Kickstarter Is Not a Store." Simulations will now be prohibited. Video cannot show a proposed product, action, etc. — only a real product and what it does at the time. Product renderings and other simulated illustrations also will not be sufficient — the project creator will have to have photographs of a real prototype."
