Umm dude, you are aware that the Nintendo figure includes all titles with the Nintendo seal of approval? Oh wait, did you actually think that 2,000,000,000 Nintendo-developed/published games had been sold? LOL! Its an umbrella figure, it should read more like "2 Billion games have been sold on Nintendo platforms"...
Although people only buy Nintendo consoles for Nintendo games amirite? I have no friggin clue. :lol
Just to put it into perspective over 1 Billion games have been sold on the
PS2, thats
one platform in something like
five years, thats using the same method I believe. Oh and when you include PS1 software sales I wouldn't be suprised if Sony's total was within 2 Billion.
