If I'm buying a game, do I really care whether they are in London or Essex? No, I don't - the game is going in the post anyway.

The UK list is a bit grim at the moment, mainly because you are mixing cities and counties into the same list. That comes across as strange, almost as if you are making a category error. Have you though of sticking to counties, or using sythentic regions (The South East, The Northwest, the Midlands etc).
