I’ve been quite disappointed with it.
To me the main draw in D2 was character customization, the ability to play the same class dozens of different ways. I like being able to, having to, make meaningful choices about my character’s advancement. In D3 there is literally no meaningful or lasting choice you make about your character other than its class.
As you advance your character you make no choices about your character, you pick no stats and select no skills. While you can choose which skills you have equipped at any given time you don’t get enough different abilities for it to matter, and you earn more slots at around the same speed as you learn new abilities to put into the slots making that sole decision you can make, which abilities to use, seem like even less of a choice than it is and it’s not much of one. Especially since you can change your mind whenever you want and many of them are gimmicky nonsense on the level of uselessness of Blaze or Grim Ward.
Skill runes are supposed to improve the feel of customization but they don’t work for many of the same reasons the skill selections don’t work. You make too few total choices and those you make can be changed whenever you want making the choices have to impact. You also have to unlock skill runes as you level so you don’t get any choice for a while and when you do it’s usually between the one or two good skill runes and the many useless ones.
The passive skills might help with the lack of customization feel. There’s an awful lot of them and you can choose up to three of them eventually. Playing with how they synergize together could be fun but you never unlock more than one in the beta so it’s hard to say for sure. Of course even then the ability to switch them out at any time always lessens the feel of customization.
In most games I’m excited by levelling up. I get to make meaningful interesting choices. I get to see how my choices play out and live with the consequences of them. In D3 I’m just basically indifferent to levelling up. Occasionally I’ll hit a level that has a new ability I want to try but that’s too rare to enjoy much.
But it’s not just the customization that’s weak. The overall gameplay has its issues as well. The combat plays more or less like D2 which is good but has a few basic issues that will hopefully be fixed such as the character stopping and attacking for some reason when you are actually trying to move and the poor UI for mapping abilities to keys introduced in beta patch 13(It was much better before that). Other issues seem more core to the design. The crowds of enemies you fight are too small. There’s no crowds of twenty, thirty, or more enemies to fight like you encountered as early as the Cold Plains, or even the Den of Evil if you were slow about killing the shamans. Instead you fight at most about six enemies at a time in normal circumstances. There’s only one area in the beta where you actually fight a crowd, a scripted random encounter, but even that ends up failing to give the same awesome feel of cutting down the huge crowds of D2 due to the fact that the encounter spawns enemies slower if you kill them slower and auto-kills all the enemies after a minute so you can potentially beat the encounter by just running in circles(I think anyways, didn’t bother to test since even with its faults it’s the funnest part of the beta and I didn’t want to waste the chance at playing it any time I encountered it).
The cutscenes are very annoying in a game where the gameplay style is all about replaying and rerunning the same area. Since the focus on multiplayer gameplay means you’ll almost always end up with people who want to skip them. Making them fairly common and in the middle of dungeons was just a bad idea in general for a game of this style. Putting all the story in the town and letting the players listen/read/watch it at their leisure and independently of the other players as in D2 was a much better way of handling it. In fact the way the story brings itself to your attention so often is itself fairly annoying. I know I’m somewhat unusual in that I don’t give a fuck about the story in most games, and certainly even less so in a Diablo game, but having the story pop up and just halt all gameplay for a few seconds every couple of minutes is just unpleasant. I again much prefer D2s style of being able to basically just play through an act without paying any attention to any story and occasionally talk to the npcs to hand in quests I was hardly aware I’d even done.
Then there’s the difficulty issues. The game is just too easy so far. It’s possible it will be harder come release but so far it’s so easy. So so easy. I can’t properly express just how horribly easy it is. It’s easy. Very easy. I played through all 5 classes to the level cap without dying. Without using a single potion. Except once when I misclicked and hit the potion button when I meant to hit the button next to it. Now it’s only the start of the game so yeah easy is to be expected, and in fact I’m not normally a person who even likes really hard games, but it’s just too much. Now it’s true Blizzard has made comments about how higher difficulties will be harder but since the game is using difficulties for content reuse rather than as a choice the whole game should be at least a little hard. Even the start. Comparing again to D2 if you charge into Corpsefire in the Den of Evil like a reckless shmuck you’ll almost certainly get yourself killed. It’s overall easy early on but possible to die if you aren’t careful or get in over your head. In the D3 beta there’s nothing like that. The enemies do such tiny damage and die so easily you’d have to fall asleep at the keyboard to die. Then it’s made even worse by the fact that almost all the low level crafting items give bonus HP. Hundreds of bonus HP per item in many cases. At a point in the game where the enemies are still doing single digit damage. And random magic items that grant 3 HP regen per second are extremely common early on. So it’s not just possible but fairly likely to end up with a character that can take hundreds, if not thousands, of hits from enemies their own level and regenerate more health per second then the enemies can do damage anyway.
This has already gone too long so I’ll shut up here before going on to trying to explain everything else I dislike, like using a matchmaking system instead of game lists, the enormous space wasting UI, the crafting system, and nearly everything else.
