Haters gonna hate but I really loved the Witcher 3 universe and the lore, didn't care of combat or other stuff at all. Never read or played anything Witcher related before that.
Now playing through it my second time after a pause of ~5 years or so on hardest difficulty where the combat actually has some depth when you can't just tank everything.
Additional information: I rarely go back to singleplayer games. For example Bioshock Infinite was a very interesting experience when I played through it, but I have never had the urge to play it again. Same thing with Metal Gear Solid 3, I really loved it back then, but I'll probably never play it again. MGS5 I dropped midgame, I don't know why.
