Sony doesnt build franchises over a long period of time. It's new ip's every gen except a couple of games. For instance the Uncharted franchise is really starting to get traction but after the 3rd Naughty Dog will likely move onto another franchise. So franchises rarely get the chance to build a brand name for themselves. Another good example is what if Sony had Socom4 instead of MAG, Dark cloud instead of WKC in the coming weeks?.
