Basically you choose 1 class and select skills as you level up. At level 10 you can select a second class, which already gives you 5x5=25 character type possibilities.

Each character has dozens of skills, plus you have this additional passive skill tree that you unlock through cleansing shrines. Then there is item customization with crafted "modifiers", adding additional unique stats and skills that you can use, all this adds literally to thousands / millions of character possibilities.

Do you want to use a double weapon shooting lightning bolts? You can do that. Do you want to summon your creatures and support them with fireballs? You can do that as well, you can push it wherever you want.

This game is very dark and grim. It harkens back to games like Diablo 2 or Titans Quest. While other ARPGs have come out since then, none have hit all the marks of what fans of the genre have been asking for. For those that wish for an updated version of Diablo 2, Grim Dawn is the game for them.

Tons of side quests, dungeons and rewards await those who are adventurous enough to explore off the beaten path.

You'll see in the game lots of lore bits that add to the world of Cairn and how it got to the dystopian state.

Relevant in modern gaming because the community can keep products like this fresh and varied, even if the developers eventually decide to slow down their updates (which they have not!). The possibilities are great with modding, while the experiences in Diablo 3 and Path of exile are a lot more static.

No forced persistent internet connection required.

Co-op is pretty convenient as players can drop in and out of your gaming session at any time. This way there is no wasted time jumping out of ones game in order to find players to play with.
