I would prefer someone with more experience to confirm, but I'm worried that's a reseal. The seal looks questionable and in the picture showing the title spine - is that some wear in the towards the bottom (far left of the pic)?
I know there was another thread regarding this specific title being resealed, let me see if I can dig it up.
EDIT - Here is a helpful thread that should help:

EDIT2 - I think this is the one I was thinking of, some good info about that specific title (and tons of BS to skim past lol):
