I haven't played one, but played a Medieval Madness at a mates place on pinfest weekend and liked it then played a Monster Bash at pinfest and liked it even more. Talking to a couple guys there, they said if i leaned more to MB then i would like AFM even more. So came home and bought one the next day.
Looking forward to seeing if they are right.
I've had a Black Night Sword of Rage premium here for a week on loan from a mate and really, really love it (nearly to the point of ordering one).
Looking at the layout i think AFM may be similar? As in big empty fan.
