To be honest, I didn't really want to answer this question, but I'm feeling rather forced to do so.
Why didn't I ask for at "more reasonable" amount? Three reasons. First: Kickstarter asked me how much, I ran some numbers, and told them how much would be needed for one year of pure, hard core work. Simple as that. I did ask a lot of people their suggestions on the subject, some of whom had experience with both Kickstarter and starting a small product based business, and they told me the same thing: Go for what you need, not what you'll get.
Second: There is a threshold where the money goes from being a very nice gesture to actually helping me take time off. It is actually about at $20,000. I could have taken six months off with that, and started to work solely on this project, but I figured if I'm going this far I might as well try for the whole year's worth of funding.
Third: I don't get all the money. Kickstarter takes a cut, so does Amazon who processes the payments. There will be taxes, and then I'll have to pay an accountant at the start of the year to help me tell the government that I'm not cheating them. By the time it's all said and done, the money that I get in hand will be roughly 75%, three quarters on every dollar.
Lastly: If it doesn't work, it's fine. I started this on the request and suggestion of lots of people interested in Mobile Grapevine coming to market sooner. If it falls through, and I'm closer to the testing phase, I'll try again to scrape together enough for equipment and travel fees so I can get to more games (~$5,000).
