I read what you said perfectly what are you talking about ?You clearly didn't read what i said. I said studio's sony started themselves from the ground up solely by Sony. All those studios you are talking about aren't studios Sony started from the ground up themselves but are developers aquired by Sony. Guerilla games was originally lost boys games and not owned by Sony. Sony bought them in 2005 only after they were made guerilla games in 2004. It is not a company made by Sony but bought up by Sony. Only Japan studio is made from the ground up by Sony
What I contested was the "most of those bought up studios now also develop for Nintendo or Microsoft" part. Which is just false.
But if you don't read my post properly it's hard to realize it I guess.
