Afm or mm, maybe mb. Those are nice neutral titles. Pac man and centipede together make a nice classic arcade option possibly in addition to the pins.
And as much as I hate to say it, put the newest Xbox in for kids. They may wreck it or steal it, but parents will appreciate alone time when it’s rainy out. Could always screw it down if theft is a concern. Just tack on 10 bucks a night and throw the money in a kitty for when it goes missing.
