Whoa. You're telling me stuff was made in non-Chinese factories once? Holy cow.
Bally/Midway/Williams (whatever you want to call them) actually made most of the cabs in the US for many years. They finally phased out arcade games in the early 2000's, but Netherealm Studios, which was formely midway's game console division (and still is, it's just owned by WB now) still uses the building to this day.
