Saw a title that's clearly a bullet hell genre pop up in Steam's deals, and I looked up the achievement page: http://steamcommunity.com/stats/Gundemo ... hievements
1 out of 8 players who bought the game beat it on the easiest setting? 0.3% of the players beat it on the hardest setting. Yes I know statistics say a lot of people never finish the game they own, but if 7 out of 8 players never finish the game that's probably not going to be very successful, especially if it's a shoot 'em up where people presumably won't be bored with the game before they get to the end unlike your generic modern game that takes tens of hours to complete.
As a point of comparison, 31% of players have beaten Civilization V on Continents setting, so at least that many % have beaten the game (possibly more), and this is a game with a nontrivial learning curve and actually takes a pretty long time to finish, so you can easily get bored halfway.
