For me its the flow and speed that the relatively-open playfield provides. Sure there are tough shots that encourage you to slow down and play very controlled but when the speed builds up in multiball or when racking up the loop jackpot it is the most fun I have ever had playing pinball. When you get Hallowed be thy name combined with Trooper multiball and you have to hit loops on the upper flippers while still hitting the ramps and orbits with the lower flippers the adrenaline rush is amazing. The fabulous rules keep me coming back for more.
