... relative to the population, of course. Actually, I'm pretty sure the UK is the country that buys the most core consoles per capita by a comfortable margin.
The UK has almost exactly 1/5 of the population of the US. But we have XB1 at 1m, which would translate to 5m in the US. XB1 is actually at 4.2m in the US. Yes, the Xbox is doing better in the UK than in the US!
The PS4 is at 1.36m. That would translate to 6.8m in the US, compared to the actual 5.2 (!).
Combined, it would be a total of 11.8m vs 9.4, a significant diffence of 25%. British people buy 25% more core consoles per capita than the US.
Add Wii U to the mix, and things are not as good but the UK is still comfortably ahead. 13.5 vs 12.4.
Congrats Brits. Big Boss save the Queen.
If however, you allow the Wii U to be defined as a core console... the deviation drops to about 10% which is negligible. After all, Americans have bought the Wii U at a rate in excess of 10× the UK...which is double what the population difference would have you believe is possible.
