The abilities and the skill tree works just like in Path of Exile, except with fewer supers and stat modifiers. Grim Dawn also has a gameplay and combat system that’s more similar to Path of Exile. So each side-mission you run in the game has some sort of connection to the main campaign. But, the main NPCs and quest givers in Grim Dawn are more interesting and usually has a good backstory that interconnects with the stories of the other NPCs. Sure you’re not going to meet a lot of interesting characters of different races, gods, demons, and angels, like in Diablo 3. As a single-player/co-op game, Grim Dawn offers the most rich and engaging story campaign I’ve seen in an ARPG. When installing Grim Dawn, I was expecting a similarly interesting story and the game over-delivered.
Unlike most Diablo 3 players, I actually loved its main story campaign. Let me explain why Grim Dawn is a great Diablo 3 alternative, in many ways. Thanks to the continuous updates, patches, and DLC that are still being released regularly by its developers, Grim Dawn has now become a well-polished ARPG that can compete with big-budget triple-A games like Diablo 3 and Path of Exile. Even though Grim Dawn was released in 2016, the game has aged and improved really well to offer a rich and satisfying experience to even the newcomers to the game and the whole ARPG genre.
