I like a lot of video games, so I'll just cherry pick some at random and think of the parts I like the least from those games:
Super Metroid: Maridia, but only because I got incredibly stuck there when I first completed the game many years ago. And fuck those parts where you have to grappling beam the floating fish things.
Silent Hill 2: The boat part. I will leave it at that.
Parasite Eve 2: The Neo Ark jungle area. It sucks despite it being a big intriguing reveal near the end of the game, and it sucks mainly because of the annoying puzzles.
Shout out to every fighting game with a character I just hate fighting against. Baiken in GGAC, Grownhan in DBFZ, Maxima and Yuri in KoF, and all the others I've forgotten.
Tomb of the Giants in Dark Souls.
How do we make Dark Souls harder? Turn off all the lights and bombard the player with giant murder skeletons. Blight Town ain't got nothing on Tomb of the Giants.
Tomb of the Giants is a nightmare. It's highly despiseable. As I think on it though, I'm not sure why I love Dark Souls so much because I despise so many parts of it. The Ghost Church in New Londo, the water-wheel elevator in Blight Town, the upper rafters of the big church in Anor Londo, and everything between Quelag and Bed of Chaos. Does Dark Souls suck? Nah. It's me that must be wrong.
