The Great Empire of Roomengoo is a colossal, efficient nation, ruled by Roomengoo I with an iron fist, and renowned for its closed borders, strictly enforced bedtime, and prohibition of alcohol. The hard-nosed, hard-working, cynical, humorless, devout population of 5.989 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, although Law & Order, Industry, and Education are also considered important, while International Aid and Welfare receive no funds. It meets to discuss matters of state in the capital city of Roomengoo City. Citizens pay a flat income tax of 81.3%.

The frighteningly efficient Roomengoo economy, worth a remarkable 1,450 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 reasonably common. Average income is an amazing 242,124 Libras, but there is a significant disparity between incomes, with the richest 10% of citizens earning 846,591 per year while the poor average 50,325, a ratio of 16.8 to 1.

Scenic mountain valleys are flooded with water as damming projects get underway, attempts to inform people about their unclaimed property are often mistaken for telephone scams, bilingual Roomengoos are viewed with suspicion, and citizens can freely debate whether Roomengoo I is a great leader or the greatest leader. 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 278,928^th in the world and 1,404^th in Europe for Most Beautiful Environments, with 6.24 pounds of wildlife per square mile.
