10/10 game...11/10 if all of the cameo gals were interactable (tifa, android 18, misty, nurse joy, rukia, etc...too many to name them all)
Most of those who simply appear in the background as extras are there as easter egg characters.
There's actually an easter egg character in the background of 10 different events no one has yet noticed. Very subtle. You have to keep an eye out.
I totally understand! Still, I can dream :P
