On a technical level this game is a masterpiece. The gameplay flows well, the artwork is amazing and the voice acting and story are immersive and interesting. I also have never had a problem with crashes that I can remember, even when playing with mods.

However I cannot recommend this game simply because it is not fun. This will invite controversy and probably insulting comments but I do not think this game makes for a good rogue-like or even a good challenge.
In a rogue-like you are supposed to get stronger with each death. To evolve and strengthen your characters until eventually you are able to overcome the difficulties, scale that wall and triumph over the antagonists. On the surface this seems to apply to Darkest Dungeon as well. However this gets marred by the presence of artificial difficulty. I hesitate to even call it RNG because I am pretty sure this is purposeful and intended: you are not supposed to win. You are not supposed to get better. You are supposed to die, in futile and frustrating ways because that is what the Dungeon Master (the developers) have decided is your fate.
This does not, to me, make a fun game to play.
Ultimately the enjoyment I take from this game gets nullified by the knowledge that even if I win, it will have very little to do with my understanding of the game or my skills as a player, and more to do with the fact that the game just decided to not screw me over just because, on that particular run.
I have noticed this kind of gameplay is getting more and more spread out in rogue-likes and I am not sure it is for the benefit of the genre.
Ultimately this game is not for me. If you like to throw yourself at a wall that, by definition, is designed to be unscalable unless you invest prohibitively long times and effort into it, then by all means, you will enjoy this game. Like I said, it is very well made. But I don't enjoy this kind of "challenge" and as such I cannot recommend it.

The whole game is one long tedious grind. It's not fun.

Since nobody will read the reviews, I'll say in this review, I'm gay and I love cross-dressing as a femboy.
