I've decided to let it go and be played by someone else for their collection. Kept in a non-smoking home. The flaws I would say are fading on the bottom of the cardboard box insert and box slipcover itself with some discoloration on the front, likely due to sun exposure & depicted in pictures.
It's much more noticeable on the box insert than the front but there is sunlight fade on the front lower right quadrant of the box. Otherwise box coloration is fine. There is some cardboard rub/rash in the top right corner and some fraying of flap edges, but all are intact and untorn. The manual is in great shape sans corner folding on the first front few pages that I've shown, likely from being left in the box incorrectly. Otherwise the manual binding is in perfect shape, and the page for mailing the strategy guide order form is 100% intact and untouched.
The cart itself is mint with no label wear and perfect pin condition. I've tested the cart both in my personal Gen 2 Genesis and Analogue Mega SG.
