Your no living world comment is a bit weird, if anything Witcher 3 is the one RPG where the world changes for real with what you do in the story, sometimes even in side quests, instead of being just different cutscenes or missing npcs. Now im not gona judge you for taste i think that would be a mistake, perhaps you are not far enough to see those thing, but again if you dont like it, its ok to not like it? Its objectively a good game in general, lots of content that many people enjoy, high production value, etc.
Now for gameplay, well it cant be worse then witcher 1 lol. But again gameplay being shit is not new to RPG genre, even in some of the best classics.
