I think that NoA runs Canada. Not sure about any other companies though.

This might help?

Maybe Mandarin and Russian would be around 5-10?
Mostly PC gamers and shitloads of pirating, little or no data about those regions though.

Most swiss people talk german, then there are a lot of french speaking swiss people then italian and then retoromanian(is that the english expression?) So swiss people probably spread themselves something like:

german 50%
french 40%
italian 8%
retoromanian 2%

Arround the world there are deffinatly more french speakers, but considering that a lot of the french speaking population has not enough money (a lot of countries in africa have french as their major language)

Also Austrians don't talk that f**thy german, whe speak Austrian damnit, they just made a farce out of our cool language and tried to rule over the world while we didn't *cough*, also the german spoke in switzerland isn't standard german its Schwiizerdütsch and its also better than german ;P

So yeah, 82mil. plus ~3mil. speakers in the US against France, Belgium, French-Switzerland, Quebec... ~86 plus some other people arround the world = 129 millions ;P minus the probably african part of that population 90 millions... now make consider gamers... hum Germans are more into PC gaming but I would think that probably both groups sum up to the same amout of gamers...

So simply take which countries matter to you in this gaming question, and extrapolate the data from that link.  Quite Simple.
