For the impatient: It's the better Diablo 3.

I tried different ARPGs in the past, ranging from Titan Quest to the Torchlight series, Path of Exile, Van Helsing series and the like. For me, Grim Dawn is an exception, since it's got an diablo-2-esque feeling. Very smooth gameplay and progression, dark and mature setting and awesome class combinations.

From my point of view the balance in higher levels isn't given by now. Being two- or threeshotted by normal mobs as melee isn't fun, enemy debuffs are extremly strong and rip your HP apart. Might be that I lack gear, but the burst is sometimes so overwhelming that you cannot counter it by usings skills/pots. Aside from this, which can be compensated through movement and CC to a certain degree, I am fully satisfied with the game. Faction system is great, weapon improvements are awesome and additional skills acquired this way open whole new ways of gameplay.
