As some people already stated, many people import UK-games due to the low pound. Being from Germany, out of my 24 wii-games I imported 11 from the UK and 1 from the Netherlands (uncensored RE4). So that must somehow give that 60 million population a boost software wise.
As stated before as well, most of my friends play games on their pc, but probably just 1/3 own a console.
Just to make it clear for the Americans again: Give me a six-hour-drive by car and I'll be able to go to one or more then over ten different countries. This doesn't apply to UK-citizens so their market is somehow more closed as well. No people buying games from somewhere else, but many from somewhere else buying from the UK.
