I've been visiting a new local arcade with a few pins; That sit-down 4p pacman is pretty fun and encourages groups of casual players to all put coins in it.
I despise the 100-in-1 multicades they have. Many of the cabs only have controls for 1p, but the software allows for 2-4p selection and then just screws you out of it. It's poorly done in many cases and the cabs have no draw IMHO.
