My point is that for some reason everyone holds up the total worldwide number as some kind of goal but it's a goal to what? If company A loses money on each system and company B makes money on each system, is company A the winner because they sold more units than company B? No, the name of the game has always been profit, not userbase. The winners will be the ones who make the most profit, not sell the most units. These don't always go hand in hand.
These companies make money off games. For every third party game, MS/Sony/Nintendo get around $12-$15 on each disc as it leaves the factory. All for doing nothing more than a few weeks of QA for cert at the end of the project. Selling 10 million copies of BLOPS? Well, that is 150 million for the console owner for doing nothing. That's what matters. So using worldwide numbers only relates to the game. Sony/MS make pretty much nothing off Madden in Japan even if both of them had 100 million units sold over there. That's why I'm saying Worldwide numbers only really matter to bullet points on PR statements and a power point slide at E3 but in the real world, it's a game by game basis.
I am interested in sales of course, I like to try to understand why some systems sell more in one region over the other instead of stupidly saying Europe=World.
