9. Hotline Miami
Units Sold: 1.6 million
Metacritic Score: 85.67
If there was one word to describe Hotline Miami, it would be crazy. From the plot, to the fast paced action, Hotline Miami that’s up next in our list of most successful indie games of all time is the definition of a short yet sweet experience. It is also quite unforgiving as when you die you have to repeat the entire level all over again. The game is set in 1989 Miami and has a very surreal treatment coupled with influences from the 1980s.
