The Great Empire of Roomengoo is a colossal, orderly nation, ruled by Roomengoo I with an iron fist, and remarkable for its avowedly heterosexual populace, keen interest in outer space, and punitive income tax rates. The hard-nosed, hard-working, cynical, humorless, devout population of 6.07 billion Roomengoos are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The medium-sized, corrupt, well-organized government prioritizes Defense, with Law & Order, Industry, and Education also on the agenda, while International Aid and Welfare aren't funded at all. It meets to discuss matters of state in the capital city of Roomengoo City. The average income tax rate is 83.3%.

The frighteningly efficient Roomengoo economy, worth a remarkable 1,501 trillion Libras a year, is mostly comprised of black market activity, especially in Arms Manufacturing, Information Technology, Retail, and Furniture Restoration. State-owned companies are common. Average income is an amazing 247,299 Libras, and evenly distributed, with the richest citizens earning only 4.3 times as much as the poorest.

Golden statues of Cats line the memorial avenues of the Funerary District, citizens complain about a burning sensation after bathing, trained plumber-burglars will clean out your blocked pipes and your jewellery boxes, and military spending is on the increase. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Roomengoo's national animal is the Cat, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Universal Church of the Creator's Kingdo.

Roomengoo is ranked 25,285^th in the world and 364^th in Europe for Most Scientifically Advanced, scoring 245.05 on the Kurzweil Singularity Index.
