Zelda OOT - A truly excellent game at the time of release, rightly regarded as a masterpiece. Pretty much unplayable by modern standards due to the really shitty frame rate and incredibly annoying menu/inventory system that make it a real slog to get through.
The real takeaway here is that Ocarina of Time was kind of a shallow game to begin with. The combat is (and was) dull, devoid of interesting decisions to make, exploring the game world is actually pretty linear compared to even LttP (and especially the first Zelda), and the puzzles aren't really that interesting. You're right that Ocarina of Time isn't one of the greatest games of all time - but it's not because it aged badly, it's that the reasons people really fell in love with it were always fairly shallow.
