Visually, Grim Dawn (GD) looks striking; almost like something out of the Dark Tower series. The story is engaging enough, a land ravaged by the conflict of two, horrific powers and humans stuck in the middle. Music doesn't strive to be anything more than atmospheric and forgettable. There is a moderate bit of exploratation and the core scavaging for loot is there as well. So overall not a bad game.
The part of the game that really rubs me the wrong way is that it doesn't feel enough to be it's own game and relies on the core components of Titan's Quest (TQ) to run. Yes, GD does run on the TQ engine so it's a given that mechanics should be seen, but to a point. Nearly everything of TQ is left within the game, the creators cobble a few add-ons, changed textures, and then released the title. The gameplay feels like it doesn't have it's own legs, that it's just playing off TQ verbatim.
If you're a strong fan of ARPG titles and don't mind playing something you've played before, then it's worth a purchase. Otherwise, I would encourage anyone else to do some thorough reviewing of the game before buying.
