At least there is a picture and description. I've had stuff sold as 'like new' which are beat up to hell.
I had the opposite problem once though - sold a Master System game, which was in beautiful condition. Many high res pics included, detailed description. Listed as 'Like New'. Which it was, it had a store sticker on the front with a folded corner, but that wasn't part of the 'product' itself and was removable. Manual and map and inserts and cart were immaculate, they even smelt new.
Guy who bought it complained about the case having 'wear' where the clips are. That is, it had been opened at least once (just tiny scrapes in the plastic of the clip of the case!) Which was fairly obviously going to be true since it was open in the pictures, and all Master System games ever would have this, they were sold in the shops like that. If you saw this on a shelf in a store in 1990 you would not think it was used.
His play was clearly just a scam to get a partial refund, I get it a lot, complaints about things clearly visible in pictures that get re-interpreted post-auction, and they always ask for a partial refund. I offered a full refund minus the return postage, but he didn't go for that, the scammers never do.
