True, but Sony's only real competition at the time was Nintendo, and they're main advantage was loads of third party support, something that Nintendo didn't have. Sony did what they still do to this day and marketed the console as the one with a multitude of games to play, while Nintendo just kindof marketed... well... Nintendo. Valve doesn't have that advantage, especially not in the console buisiness. Clearly that ball is Sony and MS's court and it won't be leaving anytime soon.
That's not exactly true. Nintendo had tremendous third party support when Sony embarked on the Playstation adventure. They lost a lot of it when they decided to stick to cartridges for the N64.
Signature goes here!
