I'm quite sad that this game has gotten so many bad reviews, its actually really good if you give it a try!
The game is updated regulary, it's way more balanced compared to the first game where you could just take a LVL 1 character, hop on a nightmare crystalworld multiplayer game and boom you're LVL 70...
In the first game it was easy to just upgrade gear into ridiculousness and instakill everything in your way.
In this game most gear only go up to LVL 16 and as a LVL 45 apprentice i still have a weapon with +5 shots and 300Dmg.
This game is a good challange, gear isnt so overpowered and the hero stats are more balanced too, where in the first game you had 300points on tower casting rate and it shoots out a line of projektiles and murder everything,
In eternity you have 400Points and the towers are now good, but not nearly as op.
The first game has it's pro's and cons, So do this.
But i got this game because: ITS a new DD game! and that it includes all the DLC for way less money than if you buy it all for the original game.
I can say that sure, you don't have to love it, or you think that it sucks compared to the original DD.
But just like everything else, give it a GOOD FAIR CHANCE, and see it as a standalone, new game instead of a copy of the old one with "improvements"
