And i agree, its not the same because Game & Watch were multiple devices that only played a single game each so it belongs in a different category.
Thanks, for the response. Despite the fact that G&W couldn't use any media for playing games,I still believe that,it is a piece of harware we should't exclude. But, to be honest, my point basically was that you can't find the numbers even in wikipedia. They make it seem like G&W wasn't even a nintendo product :p
