Nobody knows what AP will be doing with alternate art because they are just deciding. So all suggestions are welcome.
I would like to see 110% of the art redone - including playfield, backglass, cabinet and plastics, as well as art blades (extra 10%). But do it in a single and cohesive style and address the noted visual flaws. AP can then ask people to vote on which complete art package they prefer/would buy. Maybe it is 50% or maybe it is 90% and they decide to go with revised plan. This is what happened at Spooky on AMH. Existing package was limiting sales and Spooky redid cabinet and backglass art and offered it as an option. You could pick either. I believe they asked people which they preferred and it was probably 90% for the new package. Since this happened right at start of production, Spooky was able to switch over and made 95% of AMH with new art design. There are a few AMH pinball machines around with original design (between 3 to 12 and with real back glass of original design.... bluuuuuhhh). Price were kept the same. I wish Spooky had also been willing/able to refine the playfield art some, but they stuck with the original art.
If done right, the revised art package on OF should be sufficient for most buyers, and I can see no reason you would need to offer an adult version option. Do people want to see Oktoberfest held at a nudist colony from up close? I don’t, but if art direction is done to the same standards as a PG-13 movie ratings, this allows almost anything short of full frontal nudity or too much gore. Have the new artwork package be a bit more edgy, and then make it the one and only version of artwork offered. My toes are crossed for all the hot cartoon women to have big bouncy breasts and for all the studly men to have a sausage in their pants.
