I'd definitely +1 the Roadshow option. It's the one I have that my GF gravitates to the most. She also likes modes a lot(in this case cities).
RS has 4 flippers. Cool ramps with diverters that return the ball in different places. Easy to understand. *theme does not objectify women (important consideration for my collection lol).
This is the second time I've owned one. I like the simplicity and I have installed the new custom code (available on Pinside) that makes it a bit more balanced. I haven't beaten it yet with the new code.
The biggest complaint I've heard about this game is the c/w music. Personally I find it suits the theme perfectly. I'm not a c/w fan btw. Sounds awesome with an external sub but then again most pins do lol.
