FF XIII still have how to compete with Monster western franchises?

Wikipedia (the most credible source on the internet) say that KH series sales are over 12 million.

That means that KH game sales are between 12-12.5million (If it was over 12.5, it would say "Just under 13 million")

Looking at the KH game sales on VGC, they are just over 12 million.

Id say VGC is pretty much spot on with the KH sales
