If you guys wanna go off just numbers. . It is sony for sure. 2 consoles 130 million sold+. Nintendo is now at their highest with the Wii. Sony has far more fans then nintendo.
That being said its Blizzard. I know for a fact Stacraft sold like 093879384793487 copies worldwide. And the entire nation of South Korea will do as they are told. You can't argue with that. :P
