My vote hands down is Castlevania. Just an idea as have not seen hardly any new pins based off any of the long lasting games which have lasted through the years on various game systems like Playstation, Xbox, Wii, etc. As we get more selections I can add a poll with top 8 choices. Yep Ninja Gaiden was my favorite as well and I think would work along with Contra. I wish Stern would look into it besides movie after boring movie to make pins today.
