Lairshare

From publisher blurb:

There are many difficulties that face an emperor of a vast evil interstellar empire. Planets that need subjugating or destroying. The ever-present threat of a rebellion. Unreliable troops and scheming minions.

But none more challenging than having to live in a house-share in Coventry with the rulers of other, rival empires. They are not always reliable with their share of the gas bill. Someone keeps leaving the milk out of the fridge.

But by the Eye of Dread, you will endure. And find out who keeps leaving dead rebel leaders in the recycling. A comedy role-playing game with very simple rules.
