Gone Home, for sure. I probably would have felt a lot better about it if I had spent 5 bucks on it or something, but the asking price for the experience I was given is ridiculous. I figured out the "big reveal" way before the game expected me to, meaning I spent most of the game thinking that I was building up to something that never actually happened. Also, what family leaves notes and personal messages all about their house, specifically addressed to a person that is supposed to be in another country? The best thing I can say about it is that the aforementioned expectation was enough to carry me to the disappointing ending. The Stanley Parable does the whole "non-combat, first-person exploration narrative experience that subverts expectations" thing with much better execution and with a lesser asking price.
Just to pick another one, Bioshock Infinite. Please don't get me wrong, I'm not saying that it's bad. I've beaten it on normal and hard, completed all of the CitC waves, and finished Burial at Sea 1. It's probably the best showcase of visual inspiration and design in all of 3D gaming. It's just that Bioshock 1 happens to have existed already, and Infinite was a total lobotomy that I should have seen coming. I couldn't get on board with the regenerating shield, boring and ordinary weapons, boring bullet-sponge enemies, 2 weapon limit, removal of the hacking mechanic, boring and uninspired weapon upgrades, major reduction in exploration (making the scrounging mechanic feel out of place), and batshit story that starts relying on "because time travel and infinite universes" as a crutch to move things forward.
Building up to release, I was excited for a game that took the Bioshock formula to 11, exploring America and religion the way that objectivism was explored previously, with a huge open-ended city in the sky as open and free as Rapture was oppressive and crushing. Maybe that's my fault, but Infinite feels like Levine's attempt to trick CoD or Halo fans into something "deeper" than they're used to while making bank in the process. It just doesn't feel like a labor of love.
