I've been playing Grim Dawn and I'm currently fifty-fifty as to whether I want to keep playing, on one hand it's one of the better diablo-style games I've played so far and shows many aspects where it's a proper evolution of Diablo 2, on the other it also falters in some aspects where D2 didn't (I'd say core aspects, but with a game as simple as that, every aspect is core). Still, though, there was never a point at which I asked myself ''why am I not playing Diablo instead?''. Are there any other games like that, that build on the Diablo formula substantially and not in boring ways like adding romance or base building?
In GD, it is much, much faster to gear your character, that's why the devs made it in the first place, it was supposed to be a Diablo clone where you could "finish" your characters. In D2, you had to buy/trade for gear or else you'd be looking at years and years of farming for those rare drops.
In GD, you can do Shattered Realm, and if you climb up high enough, 75-76 is ideal, you get SHOWERED with enough loot to equip several characters. That's something I don't like about GD because it's TOO easy to gear up and finish your build.
The community of GD is made up of altoholics, people constantly making new builds and seeing how they can make them viable, that's where the fun in GD comes from.
D2 on the other hand is for hardcore farmers who do the same runs thousands of times in hopes of a drop.
