Konami is the only company with the gall to remake an N64 game on the N64.
Castlevania: Legacy Darkness may be the first and only remake where the original title appears on the same system. Though it may seem a bit strange to label this game a remake of the first Castlevania on the Nintendo 64, nothing else fits the circumstances. It isn't the same game with a couple bonus features and characters, so Director's Cut doesn't work. Neither do Special Edition or any other type of Edition, as there isn't a single feature to define it from the previous title. Instead, everything about the game, from the level designs to the physics to the graphics, has been altered, tweaked, or improved in some way. The result is an enjoyable, atmospheric adventure, though it isn't without a couple snags.
