What are the differences between the 2 versions?
Based on what I have seen the only difference is an included pin
The KINGDOM HEARTS HD 2.8 FINAL CHAPTER PROLOGUE LIMITED EDITION includes an exclusive official Disney collector's pin while supplies last.
The limited edition includes an official Disney collector’s pin featuring Sora and Mickey, as well as limited edition packaging.
The only difference is that the Limited Edition comes with an exclusive pin, while supplies last.
