Getting Wargaming.net to use GAME would be VERY IMPRESSIVE - I suspect they pad their "active user" claims with accounts that haven't been played for months or even years (like most game companies that have been around for a while do), but we're still looking at a potential multi-million userbase between World of Tanks/Ships/Aircraft and their "lesser" titles.
Their userbase in the USA is kinda small, but they're HUGE in Europe and seem to be pretty big in a lot of Asia.
