That might sell in the USA but probably nowhere else IMO
How about a theme based on a famous U.S city??
NYC - with a brooklyn bridge ramp and east and hudson river drop targets - Central Park mini playfield etc.
LA - Earthquake multiball - maybe even riot multiball?? and sunset srip and melrose drive ramps and light up hollywood for super jackpot.
Las Vegas - roulette spinning wheel - Hoover Dam mini playfield - hit the slot machine for a jackpot (yes, sorry TZ) you know the rest!!
You could do Paris but sales in America would be low ;-p
