The Great Empire of Roomengoo is a colossal, efficient nation, ruled by Roomengoo I with an iron fist, and notable for its ban on automobiles, strictly enforced bedtime, and complete absence of social welfare. The hard-nosed, cynical, humorless, devout population of 7.493 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 is primarily concerned with Defense, with Education, Industry, and Administration 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. Citizens pay a flat income tax of 76.6%.

The frighteningly efficient Roomengoo economy, worth a remarkable 1,979 trillion Libras a year, is mostly comprised of black market activity, especially in Arms Manufacturing, Information Technology, Furniture Restoration, and Retail. State-owned companies are common. Average income is an amazing 264,220 Libras, but there is a large disparity between incomes, with the richest 10% of citizens earning 998,664 per year while the poor average 48,637, a ratio of 20.5 to 1.

Soldiers stream their classified military operations live for millions of fans, students who refuse to pray are expelled from school, the military perceives nations hit by natural disasters as "easy pickings", and major cities run on potato batteries. Crime, especially youth-related, is totally unknown, despite the fact that it is difficult to make it through a day without breaking one of the country's many laws. 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 302,634^th in the world and 87^th in United States for Largest Automobile Manufacturing Sector, scoring -8.49 on the Henry Ford Productivity Index.
