I have been looking into many different ARPG style games to play when i'm waiting on ladder resets or new expansion to come out. I have found That Grim Dawn is similar in trade structure as Diablo 2 (most items can be used then traded again)
The story line is pretty diverse and instead of "Acts" it is one large maps with a linear progression
Builds are also Diverse, you can chose your main class then a sub class, devotions (added skill tree). abilities are chosen through skills or augments (items/item modifiers) the list goes on. I will say the builds are much less complex then POE (though i love POE)
The game has already put out an expansion with another one incoming. some DLCs that allow you to kill waves for loot. your characters as saved on the cloud and local so the same character you play with in "Single" player is the same you play in multi.
I will admit the first few hours of the game was slow, but once you understand how the game works, skills to use, how to level etc. it becomes much more enjoyable, my friend and I are working on a rushing system in hopes that it will help people get to end game faster, however right now its much like d2, if you want to level its either A: have someone rush you through the difficulties then mass kill mobs or have someone run you through the crucible rifts.
They are releasing some quality of life changes in the near future so we may see even better things from this game.
