Atomic Heart. I was excited to learn that Mick Gordon participated in the music and I got hooked by the aesthetic of the intro sequence, but the drawn-out underground lab mission series of fetch quests completely killed my enjoyment. I'd only gotten to three out of four macguffins before I gave up.
The insufferable talking glove didn't help either.
But I really enjoyed the game overall. The combat was engaging, imo. The art style is great. The story didn't matter a whole lot.
It felt like the first portal game to me, actually. Story doesn't matter, you move from room to room enjoying the puzzles (and combat in the case of Atomic Heart), and finish the game.
