This is true when it comes to the commercial success of their games.
Sony only had the Gran turismo games sell over 10 million until 2009.

I think that was true for most game companies back then. 10+ million selling franchises were the exception, not the rule for most major publishers. 

People are trying to apply modern sales standards to the gaming market of the past when they're clearly not applicable.
