Most of the sony audience just play shooters, realistic racing simulators and good action games.
You can find those anywhere.
It's not like being a Nintendo gamer and the company bails out of the game. Nobody else has Mario, not even the rip offs come close. Same thing for Animal Crossing, Pikmin, Zelda, you name. Nintendo is much more unique than the others.
For the Microsoft case, I think if I ask some people to name 5 microsoft IP's they gonna struggle.
