UI: Erm, it's not "copied" from PoE. It look similar but there are certainly differences. Not sure what the reviewer is expecting for games that are created in same engine and are same genre.
balance: Some people seem to expect all mobs in a same map should be same/similar level and that you should be able to clear everything at once - this isn't the case with Kingmaker. The developers are expecting you to come back and clear more challenging enemies later on, which I really liked. Definitely more realistic. Had to wait quite a bit to slash down Crag Linnorm hiding in caves next to a giant bridge
Most of maps are available (I.e. Don't disappear) from one chapter to another chapter, so there is really no reason to be fussed over this.
magic system: Agree with what azarhal said - That should be made toward Pathfinder pnp and not the game.
alignment:again, agree with azarhal - sound like someone misunderstood how it works. It's not a "always pick neutral good because I'm neutral good" system, it's a "you have these choices, they all have impact, pick one" system (reminds me of NWN: Shadow of the Undrentide).
dialogues: First, I didn't get an impression companions are written by several different people. Sounds like he is confusing character development with "these are written by several different people who have different ideas of companions". Second, I thought dialogue options given to me are quite flexible. I'm playing NG alignment, and most of the time I get to choose from lawful good to neutral responses, sometimes even evil options. So again, no idea wtf that reviewer is on about.
Kingdom management: I think this is most problematic part of the game and I understand why reviewer didn't like it. This really needs better tutorial and explanation,
Advisors: Why the hell is reviewer killing/dismissing advisors??? I agree that there is rather limited pool of advisors but… Killing/dismissing them intentionally makes it worse???
The game is completed by several people. I saw screenshots etc from those who finished the game on various forums.
I also have no issues with the movement speed.
Not liking is not the same as hating.
Yes, it's loud and clear you hate this game. I understand it's not your GOTY and that's fine but I'm not understanding how this game has phone game design?
