A very challenging game with some of the most intense dungeons and deadly traps.
Some of this dungeons are very inspired, 'The Pit' that is a descent in to the abyss of darkness 'The Hive' a nest full of mantises, 'Labyrinth' and 'Trench' and many others. They have a catching atmoshpere, with a lot of nice enemies to slay (or to get slayed), there are only two maps that i found heavily poor appealing to me, 'Inversion' and the final dungeon 'Dragon', that doesn't reflect the expectations ('Spire', the first dungeon, is much more a training dungeon, so very moderate in difficulty). Without considering all the long range weapons and magics that you can use to easily progress in the game. Some enemies that seams very hard to get killed are very weak to some particular magic or weapon. This game has almost everything you can ask for a game dungeon considering that this is a 1998 product.
Unfortunately the fact that to survive inside the dungeons you need to be very cautious, has given a bad reputation to this game.
I agree that mastering the controls is not for everybody, and that sometimes in some situations you have to deal with a bad camera angle that don't let you see everything (just press the First Person key, by the way. The dude can also parry and go in first person while he/she is still in the parry mode) but i'm not sure what people means when they say that this title sucks so bad that it should be removed from the history of videogames, because this is a unique title that will never be repeated in other future games. Some say that this is a Tomb Raider clone (maybe derivative) but the only thing that TB and DTD have in common is the game engine (if i'm not wrong) , the same publisher, and a female character (that is like saying that Heavy Metal FAKK is a tomb raider clone because "FEMALES!!!")
CONS: In the 1998 action game stories were weak but i can say that the ending of DTD is just 'pathetic' bacause doesn't make sense (a Diablo 1 cutscene error mby?)
