Having multiple games is just awesome. I have really found that my original games get just as much play as my Mame cabinets do.
In general here is the order of what gets played the most (out of everything that is actually working at the moment).
Victory pinball.
Crystal Castles.
Amazing Mame.
Kangaroo.
Artic Mini.
I imagine Time Pilot will jump pretty high up on the list once I get it going again. (Monitor is pulsing the HV now, and the neck isn't lighting up, may be the flyback).
