In the aftermath of the Nintendine-Segan War(read previous thread's last few posts), Britain emerged victorious. Britain was able to use the powers of chaos control to not only slow down time and reflect enemy projectiles, but also to teleport it's troops from capital to capital. Many fine goombas and koopas died in the one week war.
Britain first declared the hedgehog the national animal, as it had been the force behind the British victory. The Chaos Emeralds were placed in the royal family jewels.
It then annexed all countries it had demolished, and annexed most of the countries that were conveniently nearby. Some countries were lucky enough to become allies, such as Portugal and Serbia. With most of Europe under British rule, critics commented on the irony of the fact that while Britain had been so anti-EU, it had formed it's own EU in practice.
The British(red) soon spread all across the globe, conquering many historical territories and planning to occupy countless more(dark red). Many former allies of the defeated countries were bribed into allying with the British, such as Iraq, and South Korea. The latter was bribed with a subsidy to more or less make Starcraft free for all South Koreans.
Britain rechristened itself the United Empire, as it was far more than some petty kingdom.
The government even announced a new multi-billion dollar project which would genetically engineer a blue, immortal hedgehog ruler to reign over the United Kingdom as the first Emperor of United Empire(at which point, Parliament would be stripped of legislative power and become an advisory body, with all these powers transferred to the Emperor). This was a necessity, as everyone in the royal line of succession - except those who renounced their rights - was arrested for treason after NES games were found on the premises of each individual's home.
Until then, a Regency Council ruled on the behalf of the monarchy.
Such an impressive move did not go without consequences, however. All across the world, alliances formed, the most notable being the Sino-Chinese alliance, which was at first led by the joint ruler of both nations, the illegitimate lovechild of Vladimir Putin and Hu Jintao. Eventually, this alliance expanded, before reforming into a full Confederation engulfing much of Asia. It was commonly called the USSR + China, given it's boundaries. Boris Jintao commented that it now fell to Russia and China to lead the world's democracies...
The Eurasian Confederation announced plans to create it's own hit videogame series, to challenge the powers of the United Empire.
P.S. It's quite simple how the British are able to control so many people. Besides the fact their troops can teleport to any location to crack open a can of whoopass(or is it whooparse?), they have found a way to punish separatists that requires neither executing them or imprisoning them - roboticisation. Robotic laborers toil all across the United Empire, separatists turned loyalists.
