What It Is: For gamers of a certain age, Rare means something. Or it meant something. Before the disappointing and/or underperforming games of the Microsoft era (Perfect Dark Zero, Viva Pinata, Kameo: Elements of Power), Rare was dropping hit after hit with Perfect Dark, GoldenEye 007, and Banjo-Kazooie. Conker’s Bad Fur Day is no exception to Rare’s N64 golden age: an M-rated, laugh-out-loud platformer about the antics of a drunk cartoon squirrel formerly featured in kiddie games (Conker’s Pocket Tales, Diddy Kong Racing), Bad Fur Day is a veritable cult classic.

Why It Is Neato: Conker’s Bad Fur Day features the most disgusting boss in video game history, The Great Mighty Poo. A dripping turd with corn for teeth that swells from what can be best described as a poo cavern, TGMP bellows in an operatic tenor, “I am the Great Mighty Poo, and I’m going to throw my shit at you. A huge supply of tish come from my chocolate starfish. How about some scat you little twat?” You will never see anything like this from Nintendo again.

Why Else It Is Neato: Rare released a shined-up version of the game, Conker: Live and Reloaded, for the Xbox (yep, it works on the 360). Although it retained the original’s M rating, it was harshly censored—robbing the title of much of its raunchy charm.
