In a larger collection C37 stands out as having a unique and intrigung art package (yellow & pink, futuristic frankensteinesque theme, art on bg, pf and cab art all tie into each other nicely etc). A hot blonde is trying to raise the body temperature of another hot blonde to 37 degrees using an animated backglass. Wicked cool IMO and stands out as something special when it come to 70’s GTBs. This is why collectors want C37.
Gameplay of C37 is just OK compard to other top 70’s GTB’s IMO but in a larger collection *it’s OK to have pins that exhibit some diversity* of characterisitcs of great pins - they don’t all have to be the top players as the only way to judge. Of course I do agree that playability and fun is most important I’m just saying not the only factor. For example, I would love to own a TKO someday for yet a different reason. Not best art, not best player but rare as hell - I’ve only seen pics.
For fun drop-target happiness, I prefer my Volley but art is not outstanding - luckily they are available everywhere.
My point is that another difficulty of a having a single pin ranking is that *pins can be desirable to different collectors for different reasons AND for combinations of different reasons*.
For God’s sake though, if it’s your first or only pin, buy for gameplay.
