Their games have sold millions, regardless of how you feel about them. More than enough to justify keeping a studio afloat and grow it out. There aren't many more talented devs out there that Sony could afford to buy that would do substantially better.business of making mediocre games? If they weren't under Sony, they would be dead by now. They need to take it seriously and step up their game.
The money that's employing 200 people and maintaing a studio, could be better spent on more talented devs
Anyway, if that's your stance and you're sticking to it, you should probably get around to changing your avatar then. Just a thought.
