That's not true. You can demonstrate prototypes. What you can't do is just whip something up in Blender, do a nice rendering, and then start selling it with with the rewards being "1 widget, 2 widgets, 5 widgets, 10 widgets, 20 widgets", with no indication that you've actually done your homework to say if this is even possible.
They want people to actually have some sort of prototype, something to show for their work, rather than just a slick graphical presentation and reward system that implies that it's far closer to completion than it actually is.
