Did you just not read or watch the video? The games that came out for 1M
were not only receiving 1M. In the example of Shantae, WayForward received almost 3/4 of a million (776k) on their Kickstarter. This number is the
final amount because after Kickstarter actually processes the money, tons of people
do not pay. Indiegogo is better in that regard because as soon as you pledge the money, its taken out of your account; Kickstarter does not do that, which means the original Kickstarter amount of 950k was a bit inflated.
Using the example of Shantae again, these game developers often have publishers that are responsible for additionally monetary support. In Shantae, their publisher is a company named Marvelous USA. You can find more information about them here:
https://en.wikipedia.org/wiki/Marvelous_USA. I can't find any documentation stating how much additional capital they are receiving from this publisher, but I'm sure they aren't making a game for multiple platforms with
just 1M. Like Mike stated in his rant, they would have to work for less than 20k a year in order to compensate for it.
