'Cult classics' are a thing. Planescape: Torment has great writing, but I wouldn't call the entire game a masterpiece. I'd say it has great writing. Most people I talk to would say that. Vampire Masquerade: Bloodlines has great options for roleplaying, also unbalanced and buggy AF. People usually own that when recommending and I never hear it called a 'masterpiece.' Fallout: New Vegas is another one. Even things that legitimately defined genres, like Diablo 2 don't get called such lofty words lightly.
