Though I think I’m less susceptible to this than a lot of people, I agree with a few that have already been mentioned in this thread. God of War 2018 and its overabundance of skill trees and upgrade systems definitely was the first thing that came to mind for me. In hindsight, I wish that game had been more Soulslike in embracing its Metroidvania-ness and having a combat system that was less vertical and more horizontal. I never stopped loving that damn axe but I definitely got tired of the samey fights and power creep halfway through.
But to go all the way back to the start, Nier: Automata was definitely the most egregious case of this for me as well, to the point where it really did impact my experience with that game. I loved the first route with 2B, enjoyed it a lot, especially the spectacle and glitz and beginnings of certain narrative threads, but Route B and that unavoidable hacking minigame got really old really fast. It was a neat game in the end, and Ending E truly was… unique? But I skipped out on a lot of sidequests and missed a lot of stuff that I think would have given me a deeper experience because, after 40 hours, I just couldn’t stand another 5 hours of that combat system. It just felt so pointless and boring, and I truly wish that game had just been a walking sim.
Or even—it feels weirdly sacrilegious to say this—I wish it had just been Death Stranding. In the way that Death Stranding had a few big spectacle bosses but was mostly just about traversing a world. I don’t feel like Nier would have lost much that way, because those bosses were really the only times I felt engaged in any way by the game’s combat.
