Wait, wait, wait....Gameworks has an AX machine????? Holy crap I need to go ASAP!!! I haven't been there in about 4 years. Love that place, 8 player Indy 500 is so much fun.
There's another nice arcade in the Chicagoland area called Nickel City (used to be called Super Just Games years ago) all games are nickel priced. The most expensive game, from the last time I went, was 30 cents, and that was DDR. They also have a large free play area with classics like, Track and Field, Soul Edge, Super Off-Raod and many others. It's in Northbrook (or Deerfield on the boarder) on Waukegan Rd. (Rt. 43).
