Quoted from vid1900:I don't think that the AFM is truly NIB.
You can see that the back of the backbox has been repainted with a black paint than has a different amount of gloss than the paint that is in the field of the screened lettering.
This is one of those things that you might miss in person, but becomes glaringly obvious when the contrast is highlighted by a digital camera. Same thing with classic cars that have been restored.
Not trying to cause any trouble but this is pretty clear now that Vid1900 points this out: a NIB game simply wouldn't show this type of touch-up evidence.
You might want to present this evidence to the seller Wise_Guy.
Post some interior pics if you want them analyzed for more amo; but if you're happy, that's all that really matters.
