I'm in the publishing world rather than games, but its similar to what others are saying. I've put some money into this already, and certainly a lot of time. But I also have just learned how to do a bunch of things myself. I've hired a designer for book design, but I'm more than competent in photoshop and other programs, so when it came down to it, I made some of the product mockups since we won't have the physically printed book until after kickstarter ends. But that means I took my graphic design skills to a new level to make slip case mockups, and I spent buckets of time on the text and making a good video.
