While debuting as a family-friendly series, starting with Conker's Pocket Tales, it has shifted focus to mature audiences with the release and development of Conker's Bad Fur Day; during its development, it was changed to include graphic violence, profanity, and other adult material, which earned the game a Mature rating by the ESRB, with an advisory on its box.

[8][9] Conker the Squirrel, who previously appeared as a family-friendly character, was retooled to be a foul-mouthed, fourth-wall breaking alcoholic armed with guns, throwing knives, and a frying pan.

[6] The first level, the beehive, added machine guns shooting wasps which Rare found funny and kept going with this idea to be raunchy and different.

[11] After two more years of development, the game emerged as Conker's Bad Fur Day, which targets adults rather than children with its mature content.

Thrown into prison, Conker is faced with the prospect of execution and the game starts with his escape, ball and chain attached, from the Castle's highest tower".

[17] After Live & Reloaded, Rare started development on Conker: Gettin' Medieval, an online multiplayer third-person shooter game, but it was ultimately cancelled.

The campaign, titled Conker's Big Reunion, is set ten years after the events of Bad Fur Day and Seavor reprised his voice role.

In 2015, Conker's Bad Fur Day was included in the Rare Replay video game compilation for Xbox One.

[24] Critics have noted that the storylines and variety of characters for Conker's Bad Fur Day and Live and Reloaded in combination with the crude humour and seemingly innocent graphics are noteworthy appeal to mature audiences.
