Only thing I don't understand on this discussion is why people are confusing "entering the level" with surpassing.
The OP and thread only means, that after 4 gens Sony have been consistently putting out games that sell on levels that Nintendo have been doing for a very long time. in PS1-PS3 you would only expect GT to cross 10M, but then Uncharted and TLOU appeared and got near it still on PS3. But just this gen we have come to a situation that a Sony IP can be expected to cross 10M, instead of just acting surprise it crossed 5M.
Has there been anyone who confused entering the level with surpassing?
The problem is on the people who think that crossing 10m with a few games puts Sony on the same level as Nintendo who have had several IPs surpassing the 20m mark in the past and Switch allows Nintendo to do that again after a botched generation with the Wii U and 3DS. When 10m is considered a different level than 5m, then 15m constitutes a different level than 10m, and 20m is a different level than 15m, and so on.
For console sales, you wouldn't make some arbitrary rule where everything above 50m should be considered the same level either. You'd insist that there's still a clear difference between 50m and 100m, for example.
About the only agreement I can see being reached for the topic at hand is that time should be the judge, so this thread can be bumped whenever new sales information gets released and somebody cares enough to post an update.
So now any Nintendo game that doesn't sell 20M I'll consider to not be at Nintendo level... we can really reduce a lot the games of Nintendo level on their platforms...
Also we can say that Wii didn't get to Sony level of HW sales because even though it is near to what PS1 got and higher than PS3 it is much lower than PS2 or PS4.
Or we can say that Nintendo HW doesn't sell SW at comparable rates that Xbox and Playstation do because it doesn't reach about 12 SW per HW.
You know you were just trying to downplay it.
