Five Third Party Franchises Sony and Microsoft Might Want to Court

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.
