Just played a few games on an Elvira LE last night. Brand new right out of the box. And although I agree with you that many games share a very similar design. I have to disagree and say that my uncle, son and myself all thoroughly enjoyed playing Elvira. I thought it played fast, had cool features, some of the best artwork ever, and multiball/code was killer. Gargoyals are amazing. Diverter inside the house kept the ball flow unique and interesting. Ramps were smooth as glass. Scoop was pleasant to shoot for. Everything just seemed to fit.
Admittedly I have only played a few games. But I am impressed so far.
Thanks
