It should have way, way less complexity than Pillars of Eternity. My experience with that series is rather like death by game manual.
To be fair, it being based on D&D will keep it within sane boundaries, but it should not be something you need to read a 200 page long manual to get into.
One of my favorite memories of Baldur's Gate 2: Shadow of Amn was having that massive spiral-bound game manual that came with the game. I mean, it wasn't anywhere near as large as the Skyrim Special Edition Hardcover, but still, I hope you get the point.
