They have to justify the expense of making FFXIII with spin-offs / sequels in order to reach the desired profit after the initial investment. They probably hit that point a while ago and this is probably just ease of sales, lack of creativity, and going the Activision route of publishing. I'd like to see something new and original (I don't even have to like it, I just want to see something different). If you don't like 13 or didn't care for it, it's a rather boring point in the FF franchise for you to be in.
Invading world of the guilty as spirit of vengeance The guilty pay the price. I hate Square-Activision's FFXIII and its slew of cash-in spin-offs & sequels
