i can't follow VDs logic for asking 1/3 of the real cost when you can just ask for the full cost. the way i see this, people will not find 12 million more intimidating than 4 million when they are contributing 100$ each anyway.
First, it's a deception factor. People are sheep. they only back if they think others will back too. Second, it's a marketing thing. you obviously need more money no matter the outcome. Third, asking for what you actually need is very risky. If you come short, not only will you not be able to make another console crap with bad pc porting for your backers but you also
create an impression that people aren't interested in your project have to live with the truth about how many people are interested in people not lying to them and getting the game that they backed.
Basically there is a YUGE difference between "the truth" and "the shill". Plus collecting 70-80% of what you actually need (by lying to everyone) will allow you to
make it to early access make console versions, for example, or seek additional funding from a publisher (to make the whole kickstarter campaign just a marketing scam and still go to publishers instead of getting your independence and using your independence), etc.
