It's not a bad game, but it is a game for a very specific type of player and it has very little interest in being accessible to others. This is a game for obsessive optimisers and wiki-readers; a game about optimal choices. When you first play it is a disgustingly hard game, because you just don't know how the game systems work. Once you know how the systems work, there is no real challenge at all, not even the RNG, because even the bad rolls are a known quantity that you've accounted for. This makes for a deeply frustrating experience, because the game does almost nothing to teach you about its systems, to the point where you simply cannot learn them from within the game. It's also important to point out that this is not a "Souls like" RPG. Souls games can have so groan-inducing deaths, but you just go back to the bonfire and try again. DD will wipe hours and hours of play with little warning and tell you to just deal with it. Souls-like punish overconfidence by making you take 100 tries to kill Ornstein and Smough, but they don't punish you by making you start the whole game over. If you are the kind of person who enjoyed gaming back in the days of Terror From The Deep, you probably will like DD. But the old XCOMs were games made when you didn't have instant access to the best strats. If you want to be good at DD, just read the wiki, and at that point the game plays itself.
