Played for about an hour. Game is quite good. Everything is very intentional, skills synergize, it is VERY SLOW compared to your typical ARPG, so be prepared for that. Plays more like a top down 3rd person action game (at least at first).
Visuals and animation are unmatched, except maybe in the character screen, where D4 seems to have put most of their effort.
There is some story, good voice acting, I'm hoping the characters take more of a role in what your are doing rather than just talking every once in a while.
I can see how POE1 players may not enjoy this as much, this game doesn't seem particularly conducive to blasting.
Also the bosses are quite lovely, you have to been on your toes and mix up your abilities (eg. take down their armors, or try to stun them), they animate incredibly well and even a basic sub-boss in this game puts some of the D4 act bosses to shame, I'm not exaggerating.
I tried Merc and Monk. The Merc is fun switching up between ammo types, but you're going to be doing quite a bit of kiting at first. The Monk is more tanky and at first the abilities are a bit more flashy, but they both felt balanced.
I think given the amount of hype there was and the enormous number of youtube videos I've watched of this game, my expectations were quite high, and this game managed to match them - always a risk to burn yourself out on pre-release media.
This is well worth the $30 and you'll get a lot of fun out of it, and each class plays so differently it's really conducive to starting multiple characters and just experimenting, with a VERY expansive character building system.
