I have the feeling that this'll have limited interest, but I made it and in case anyone else might want it, I'm giving it to the world.
Wales is one of the constituent members of the United Kingdom, one of the six Celtic Nations, and former province of England and later, Great Britain.
They had no representation in Rise of Nation. Admittedly, they are of relatively minor historical significance, but the British used only English and Scottish cities (no Welsh).
I wanted to be able to play as them for their campaigns against the Roman occupation, which were supposedly quite fierce.
Also, I felt like playing as them.
They will be replacing the Dutch.
They have the Power of Resistance, which is the exact same as the Dutch's Power of Commerce
Their Unique Units are the Dutch "Armed _____" line and the British Longbow line.
Their cities are all Welsh cities, and after the first few, is in random order.
Their leaders are all Welsh rebellion leaders from the age of Roman Occupation.
