Hollow Knight
Hollow Knight was revealed on Kickstarter in November 2014, the developers needing 35,000. The game passed this goal, raising more than 57,000 from 2,158 backers, allowing more content to be added and another developer to be hired—technical director David Kazi—as well as composer Christopher Larkin. The game reached a beta state in September 2015 and continued to achieve many unreasonable goals to add in more content after an engine switch from Stencyl to Unity. Some of the goal content, such as The Abyss, still made it into the game even though those goals not having been achieved, although with a lot of content was cut.
