England, Wales and Scotland are not seperate countries. The country is United Kingdom. If you are going to act like this just for the United Kingdom, there is going to be tons of discussions about other countries. The official, sovereign state is United Kingdom so keep it that way, although all you proud English, Scottish and Welsh nationalists might not like it.

Get Scotland and Wales of that list.
You forgot Northern Ireland, Not even sure if any Northern Irish people play cRPG atm...
The only other people who want to see another country split is Germany, but Germany is still just one country. The United Kingdom is a sovereign state with four Countries within it, they are still four seperate countries, but are just all ruled by the same Monarch.
It is a country in its own right and consists of four countries: England, Northern Ireland, Scotland and Wales.
Germany, is one country with 16 states in it. The same as America is one country with 50 states. A State is not the same as a country, no matter how large or small either of them are. Most States in America are bigger than England but they still are not classed as their own country.
