This achievement is granted to those who reach the estate by completing the tutorial. With this high percentage, it looks like new players are having difficulty getting attached to the game. The interface is nice, but there are not enough descriptions and tips on what to do next. The tutorial is important in any game as it teaches you how to play. In Darkest Dungeon, the tutorial is lacking, which could stop people from continuing.
The game has had success, despite the achievement results. It is #34, on Rock Paper Shotgun’s list of The 50 Best RPGs on PC. But, just think of how great it could be if the tutorial was more user friendly. If people aren’t grabbed by the game from the start, there could be bad reviews and returns. The developer, Red Hook Studios, may want to rethink their tutorial if they want to keep their buyers happy. People expect the game to be challenging–not the tutorial.
