Wax it and play it. Not all games have to be restored.

Indeed just leave it and play it. The damage doesn't look that bad, there are worse games that are still played and enjoyed.
Put a clear lexan protector over it (buy one or make it yourself) if you want to prevent more damage and if it's not smooth enough and if you're not against protectors..

I agree with the protector solution.
That's what I do.
I'm not good enough to do touch-ups on playfields, but I also like the used aspect of a game that has lived.
So being able to play it this way without using it more is a pleasure, in the end.

I wonder if anyone makes insert decals for it? If so, I'd put insert decals on the inserts that have missing art, then put a previously mentioned clear plastic playfield protector on it. If nobody makes insert decals, then I'd skip that step and simply put the playfield protector on it. Maybe later when you're feeling more adventurous you could learn how to make water slide decals and make a bunch of little Williams money graphics for all the missing money art, lift the playfield protector and apply it, then put the playfield protector back on. Whatever you do, have fun with it.

Wax it and play it. Dont see the issue

Believe it or not, the average person (non-pinhead) would not even notice this. Don’t sand it down further destroying. Just leave it and enjoy.

Yup I came here expecting to see a destroyed playfeild. That one isnt that bad at all. I have much worse on half a dozen of my games.

I have sold games with playfields like this at a full retail price.

As many said, most people don't care.

Millionaire is such an ugly game I really don't see the difference. Might as well play it rather than worry about going full resto on it.

Unless you want a mint Millionaire. Then go whole hog!

You could scan it and make your own decals in illustrator or photoshop, although that can be hours and hours of work.

You can get decal paper that is either white or transparent.

Sand it down, tell everyone its a "white wood", sell it for $65,000...

Windex the dirt off and play it.

I think it’s awesome that so many people agree the best solution is to wax it and play it, and maybe a playfield protector so it doesn’t get worse. Not every game needs to be a prom queen.

One of my favorite games of all time was an EK that was way worse than this. Between me and a friend we put over 5000 games on it over the years. There is something liberating about a machine that you just play without any concerns.

I have an ALPS and can help you if you want to take it that far. How much white lettering is there?

I've tackled much worse than that, so that game is eminently saveable and restorable once the time comes.... you'll know when it does. Meanwhile, I agree with the protector for now, until then.

I vote for wax and play, its not taking away from the fun of the game, gives it some character and a tip of the hat to you for bringing it back from the dead. Well done!

Wax and play!

Was expecting to see a much worse playfield from the thread title...

I have a pin like that, we take it camping & run it off of my little Honda generator.
It’s nice to have one you don’t have to baby.

Man ! Take pictures of that, pleaaaase !

Otherwise, there's one for sale, and on my side of the pond...

That one looks worse the the OP's

Not sure about that.
There's only one bad area, but still, not worth shipping it.

just wax and play as any anything you do will make it worse and much more noticable
