I'm one of the least politically correct people around and I drew the line on the monkey. I wasn't horribly offended but it's just not appropriate anymore to have imagery of women getting groped without their consent. Not sure there was ever a time when this was appropriate as it's better known as sexual assault.
At a time when we're starting to get women into the hobby we don't need images of women getting groped on new pinball machines. Unfortunately, there seem to be idiots in this hobby that can't keep their hands off women and can't keep from blurting inappropriate comments around women at pinball tournaments and location play.
I have no criticism towards the API artist either. I produced a graphic for a flyer at work. Someone became offended with a small "element" on the flyer and I got a call from the Office of Diversity at my workplace. I had absolutely no intention of offending - but in hindsight I could see how it was taken wrong. I was very embarrassed and recalled the artwork immediately. API did the right thing here and I applaud them for doing so.
There is one company that sells alternative, R-rated translites. You could always approach them to create a sexier translite for Oktoberfest. I would rather see a sexier translite than a perverted monkey.
