Kapi didn't find it obvious, but you said it was obvious, in a reply I made to kapi.
I already talked about Kapi. Here is his post again, since you must have forgotten:
"Nope that is definitely an opinion. To call them best selling would be a fact but calling them greatest is highly subjective and so only an opinion."
He explicitly states that Nintendo are the best selling software publishers. He agrees with this fact. It is obvious to him.
He disagrees with your interpretation of "greatest."
His post doesn't matter anyway because - like I just said - a claim does not have to be obvious to everyone in order for it to be obvious.
And I agree with your statement that a claim doesn't have to be obvious to everyone in order for it to be obvious, however the smart to moron ratio is something that neither you nor I can know.
Due to that, I feel the responsibility to post it.
Moreover, that fact is important for the topic, as obvious as it may be to some of us. The reason is that Nintendo have the power to sell their consoles all by themselves, they truly are unrivaled. That affects who wins by default in my opinion. The initial fact may be obvious, but its implications may not be. (So much so that I'm having to clarify the purpose of my original post here.)
