Long-version: Grim Dawn is an action-rpg set in a post-apocalyptic world, where monsters and all kind of weird creatures and crazy people lives. I'm not covering the story here, but it offers a nice background to the game.
The game shines on the customization of your class. You can combine two different classes to form a unique one. Or, if you prefer, you can attain to only one class, not chosing a second. Each class has dozens of skills, and there are hundreds of skills combinations. Itens can give you skills too, making the possibilites even greater. There are runes that can be attached to the itens, and guess what? They can give you skills too! Just think about the possibilities.
To complete the package, there is a constelation system, where dozens of constelations offer bonus to attributes, damage, resistances, and when a constelation is completed, it gives you a modifier to a skill or a completely new skill.
The graphics are good. The design of the monsters and the level design are very nice, but I feel that the main character could have got more attention. Maybe a character customization? It'd bee nice.
If you want a deeper experience with an arpg, and like me, didn't like poe, this is a nice (if not the best) option out there.

COMPRE COMPRE COMPRE.
