3.) Final Fantasy
Say what you want about the Final Fantasy series, but it is extremely popular in both western and asian territories for more than a decade. The franchise is also a commerical success since Final Fantasy XIII sold more than six million copies and it even spawned a sequel that sold three million units so far.
The MMO Final Fantasy XIV also did well commercially and helped Square Enix to a profit. I think that this would be more beneficial in Sony's hands since the PlayStation was its exclusive platform for the longest time. Sony also has a strong footing in Asian markets which Final Fantasy is undeniably popular in.
