Ummm...pretty much all Sony studios were acquired:
Nowhere near the same as buying a company like Bethesda who developed, published, and was already a successful multiplatform company. Sony bought most of these developers while they were still growing and independent. Only exception really was Insomniac they were practically a 2nd party developer for them for years. Any more weaksauce arguments for today? You're on par for the course as usual.
All of them or at least the vast majority of them were multiplat devs which as the TC put it - acquired just to keep their games from being on other systems since Sony can't develop their own teams besides look at the title.
As for acquiring the publisher, well they would want to just that Sony doesn't have the money to do so. By the way, why are you upset over Bethesda, haven't you made countless threads about how they suck? Any more bu*thurt replies? You're par for the course as usual.
