Stern has done it in the past. It makes sense to me that when you have a great layout, use it for several themes. Band themes are popular so just use the same layout for several band themes. Keep the same basic rules and just change out the art and songs. I'm really liking the layout of Iron Maiden but still on the fence about the theme. Metal bands do go good with pinball but just not sure about this one. It's better than a lot of other themes used for pinball, I will give it that. Just not really what I am into at all.
