Skyrim. It doesn't help that I saw a friend complete it first. But I kinda got lost, didn't play it for half a year, then went back into it, noticed my confusing, intimidating quest log with no idea what the main goal was, said "fuck that!" And proceeded to devour the entire console then throw myself off a ten story building. Am starting to think that last part may have been a dream though.
Gone Home. A classic case of knowing the story before playing. It felt like watching Columbo on an especially dumb day after he started solvent abuse. I completed the rest of the game in my head, it was much quicker and I'm sure there were space dinosaurs too.
Murdered soul suspect. I have never been annoyed as much at one question until this game, that repeats that question for every. Fucking. Case. "What is the most relevant fact/clue?" They're all pretty fucking relevant, and what the hell do you even mean by relevant?? It seems to change with each damn case!! Lay out some bloody ground rules or a glossary or something!" Not bitter, just a little dumb and hate vaguely worded questions with even vaguer answers, especially when they judge you for not reading their particular way of thinking during each case's planning process. So much time wasting.
