Chambersburg Mall has a small arcade still that has one or two classics and a pin or two. Exit 20 Scottland Exit off I81.
Then there is Funcastle which is about 17 miles south of Chambersburg. Located east on route 16 about 10 miles plus once you get off I81 on your right. It is a putt putt, go cart, arcade that has a pin, neo geo mini, ms PAC, galaga and couple other classics.
Hershey Park is about an hour north but they got some killer game rooms but I doubt u want to spend 40 and then some to play games.
Then there is Mickeys which is in Greencastle Pa. West on route 16 and then south on route 11 it is almost immediate on you left. They have do, ms PAC, galaga, and some other games and have great food and icecream.
