Nothing against THIS game, I think Moochie is doing a good job.
Most of all it requires planning, not just investing.
I supported so far about 40 games on kickstarter. The problem I see with the supporter system is that the supporter attracts amateurs without any plan how to do things. When you go to a crowdfundung platform, you need to have at least some graphics, maybe a demo to show with gameplay. Of course also there you find people who in the end are not able (or willing) to deliver the product. But my personal opinion is, that the system filters out more of the worst people who may get discouraged when they see there is actualy work to be done, before people give them money. And people have a certain idea of production costs. One making a MMO for 5000$? Not gonna happen. Investing in that would be stupid.
There is some logic in putting a ongoing series without meaningful gamplay on a supporter platform and release episode. On the other hand it makes it really really complicated to include some complex puzzles that require elements from different parts of the game, these have to be planned ahead. It depends a lot on the type of game one is trying to create.
And of course when there are supportes, they (or some of them) keep demanding certain types of content and the maker has to please them in order not to lose them, put stuff in his game he never intended to and which most likely is to break immersion or ruin the gameplay. With a what-you-see-is-what-you-get system that danger is a lot less present.
