Here in Appleton, WI we have Funset Boulevard, roughly 10,000 sq ft of newer games with some classics, pin, and redemption games, laser tag, bumper cars, etc. It is attached to a movie theater.
For older games I hit up JJ's Laundromat, I'm guessing it's a dude's collection since they have ST:TNG pin, Data East Star Wars pin, Raiden 1 and 2, Pac man, some 'Classics' compilation cabs, turbo outrun, etc. Not an arcade per se, but more games than any of the other places around here.
If anyone knows of a decent place up in Green Bay maybe you could post it? It's a bigger city so it SHOULD have an arcade..
