Quoted from CrazyLevi:

In almost 20 years in this hobby I've NEVER heard an old NIB vault game horror story. JOhn's Jukes was selling 20-30 year old NIB Black Knights for years and they were always gorgeous. Boards were always fine. Even rubbers looked beautiful.
It makes for nice copy but if you buy an ancient NIB game, you are going to get a beautiful game despite what the seers of doom may predict. Because the game has been sitting in a box in storage. The OP probably realizes the game is worth more in the box to the right person than it would be opening it.

The absolute worst case scenarios here - acid on a board or rubber that needs replacing (GASP!) are complete non-issues for a buyer of a novelty like this. Boards are plentiful, reproduced, plentiful, and relatively cheap. Regardless, seen plenty of photos of 20-30-year old games being unboxed and the batteries are ALWAYS fine. Who know? Maybe they made 'em better back then.

Dont teach her how to check out internet history, she'd be wishing he played that instead.

Really?
Your wife would care?
I've got a Sexy Girl plus two different Playboys, and all my little nieces and nephews, aunts and uncles (and my 80 year old mother when she was alive) have played them.
No one has ever been offended, or tried to shield the children's eyes.
I've had many work parties where everyone was invited to bring their kids, and no one was ever like OMG! The kids don't even pay attention to them, they play one ball, and then only want to play Xbox on the 10ft screen.
It's a big nothing.
From what I've seen, kids have all the real porn they need right on their phones.
