TL;DR: You really have to like how the combat plays and accept the fact the game is closer to Diablo/Sacred with Dark Souls combat than Baldur's Gate in terms of how RPG-y it is. Otherwise you can end up being disappointed.
Some minor annoyances (minor for me, the might be a deal breaker for someone else, so I am listing them below):
- If you want to hear the Narrator you're forced to enable music.
- The quest log not having all the informations you need, meaning you can end up not being able to finish the quest if you don't pay attention to what NPC is saying or forgot it after returning to the game a week later.
- The other Champions are immortal and will harass you non-stop when you get all the Crystals. They aren't that difficult to defeat, but having to kill them over and over is annoying as they ressurect after 3 days. You can get rid of that by picking the solo campaign (the rewards from defeating the other Champions are not really worth worrying over).
- The hidden repair equipment button in the crafting tab(!). I didn't feel the need to craft anything (most stuff I found or got from quests is better anyways), which is why it took me so long to find out there is an option to repair equipment outside of crafting benches in the dungeon locations.
- Sometimes (mostly during intermissions when you enter a location for the first time, but this is true for some "lore" NPCs as well) the exchanges are too verbose. I like the idea of giving the player the feel of what a given location is, but they are trying too hard to provide information to the player at the expense of making the whole exchange believeable. The result is that these scenes sound artificial/fake, like a poorly executed play.
- In case of larger enemies it can be hard to judge the distances, and they can attack VERY fast (trolls, for example), which can hurt a lot.
- You have to go to the inn to manage your inventory. Considering you can't get attacked in a city/town/village I find the need to go to the inn just to unload my inventory or change my items to be a needless busywork.
- The AI companions can be helpful/useful, but I found them to be more of a distraction for enemies than something I am grateful for. In short; don't expect them to play tactically.
Things I like:
- The combat. There is plenty of playstyles that change how you approach the fights. There are also many skills, weapons and armours to pick from. It can also be quite demanding, even on the beginner difficulty (you have to win the game in order to unlock a harder mode).
- The world. It feels like a combination of Tolkien's traditional high fantasy with some elements from the Game of Thrones and for all its fault with the writing, it gives the world some sense of history and cultural identity, even if the delivery does not always land.
- Vorastel the Dice Game. This one is quite neatly executed, allowing for some strategy in a game consisting of - essentially - random dice rolling. It is also a nice way to make some money, outside of raiding the dungeons.
- The visuals are fantastic. The game gives me the Sacred vibes in 3D and the loading times are nigh-instant (although I have also a very strong PC, so your milage may vary).
- I adore the tabletop-y map. It is a joy to simply look at. It also has some nice functions that help you find locations (atlas of locations, I think it's called).
All in all I have a blast playing this game. It is really hard to put down once I start playing, because doing "just one more quest" or "just one more location" is quite addictive and I enjoy the combat wholesale.
