A debatable thing. Here's why:
Say some dude has a game idea. It's a fairly complex space-based strategy MMO. The dude starts working on a design plan, because he's good at that. He lays in the design foundation of the game: all items, all ships, all celestials, game mechanics, skill tree, interactions, timers, formulas, everything design-related. He even builds a database and generates the "universe" in which the game takes place. That's a few hundred work hours right there.
But the dude has no development skills and not nearly enough funding to hire a team and actually starting to produce content. He would think Kickstarter would be a good place to sell his idea and maybe get enough funding to start working on a prototype. But wait, everybody expects a working prototype, so where does that lead us? It's a rock-paper-scissors thing.
I understand why a potential backer would want to see something palpable before committing, but at the same time something palpable can't be built unless backers commit. What would be the alternative? is there a way out of this?
