The sum of NA+UE+Japan+Australia usually gives you 96% of the market . Make the proof with PS2 .106 million units sold . Europe:40 NA:40 Japan:21 Australia:3 Total in these markets =104 . Sadly South Africa ,South America ,Hong Kong and the others you cited dount count . Second ,European Union countries . UE has 27 countries right now .Rumania and Bulgaria just entered ,and another additional 10 of the East Europe (former communist Europe ) some 2 years ago .Well ,those 12 countries dont count ...they simply dont have official distribution and their income per capita is very low ...some of their elites must be buying some imported consoles but the numbers for those are already accounted in the main 15 countries core of the UE .From those 15 countries you have 5 big countries ;UK (that includes Ireland and Scottland mind you ) ,Germany ,France ,Spain and Italy .The others are just plain small ....Greece , Holland ,Belgium ,Swizterland ,Lichstestein ,Denmark ,Andorra and the others are most of them not even 6 million(and some only some thousands as Lichstein and Andorra ) people and their videogame market isnt very developed in other cases .Portugal, Greece and Austria would be middle-sized countries but in the best scenario just a 25% of the others as France or Spain . For the later years the data has been that UK signifies some 40% of the UE market ,with 20% going to Germany ,18% to France ,7 % for Spain ,7% to Italy ...that would live the remaining 7% for the other countries ...and it makes sense ...between Greece,Portual ,Austria and Holland they must be equal to one of the big markets (Italy or Spain ) and the real tiny ones(andorra ,malta ,lichestein ) dont account for nearly nothing .
