Dismayed by its political turmoil and isolation, the queen invokes the royal prerogative to dissolve parliament and take control over the county herself in an attempt to make Britain great again.

Recognising the difficulties in re-conquering a quarter of the Earth's surface, the queen creates a new space organisation called SPIFFING (Special Planetary Investigative Force For Inhabiting New Galaxies[3]) with the intention of establishing a galactic British Empire.

On board the HMSS Imperialise (a converted Mini Cooper), Captain Frank Lee English, along with his Welsh subordinate Sub-lieutenant Aled Jones, lead the colonisation effort.

After exploring the planet further, English and Jones discover two French colonists; the first man, Antoine, is a short Napoleon lookalike whereas the other is a gorilla named Pierre.

Antoine explains that he intends to terraform the planet and plant masses of vineyards so that he could produce fine wine, with his ultimate goal of ensuring that the people of his empire will eat crêpes, wear berets and ride bicycles.

[3] Due to the outcome of the United Kingdom European Union membership referendum, the game had to be rewritten and some jokes adjusted in order for some parts to make sense.

Barr compared the feeling of disorganisation with games like The Sims and The Curse of Monkey Island, where he opined that the player always had to suggest an action as opposed to physically participating themselves.

Barr took further comparison to traditional point-and-click titles which involved mundane gameplay tasks, and stressed that he wanted to make Her Majesty's SPIFFING more responsive and immersive.
