I am one of those people who liked PoE but bounced off PoE 2 repeatedly. I think a lot of good reasons have been mentioned here already but for me:
- First, the marketing and communications around this game were practically non-existent. I follow this shit both personally and because of my job, and I was barely aware of this game right up until launch.
- The game starts way too slowly, with a lore-heavy sequence that just kills things dead right in the beginning. You could make the case that the game never recovers. The long-winded scene of table-setting with Berath would have been much better broken up and sprinkled over the first 1/4 of the game. You get your marching orders way too soon.
- The world is a confusing mess to navigate. I'm all for open world exploration but look at something like the The Witcher 3 for inspiration here -- gate off a small tutorial area that takes 3-4 hours to get through so the player actually has a sense of what the fuck is going on, where they are, etc.
- The whole ship combat thing is a boring, unfun mess. The entire ship minigame needs to fucking go.
- There is no direction in the beginning of the game; it is easy to miss what are critical companions (Xoti, for example -- your only real fucking healer!) and you can quickly get into dungeons and situations that are way above your level without knowing it. This isn't the baseline difficulty of, say, a Morrowind where you can stumble into a cave, realize it's too hard, and come back later. This is the difficulty of getting all the way to the bottom of a fucking dungeon and having to turn around.
- Too many factions are hurled at you in the beginning, with no reliable way to keep track of what is going on. The confusing names, the constant use of slang and/or patois, makes the story in the beginning tough to follow. What the fuck is going on, and why do I care?
- Group size of five instead of six. Why? Why did they fucking do this? It's terrible. With the sheer number of classes, multiclasses, subclasses, etc, such a low party size creates pressure to fill necessary gaps. There are only a few NPCs (including your own) you can really experiment with.
- I like the insane class system with its subclasses and multiclassing, but it is all too much, too soon. The game suffers from multiclassing, imo. They should have ditched it, or done like 2nd Edition and put racial restrictions and not let you multi-class kits.
- Just a really uncompelling story, narrative-wise. I never got the sense that a giant crystal god smashing around the coastline was something I had to care about (or indeed, that it was actually even happening).
