Quoted from ChadTower:Right now the key is anything other than 40 year old male themes. That is all Stern makes.
That may be true now, but it's because of the home buyer. Here's a Gary Stern quote from almost 10 years ago:
"We basically think we have two markets, two demographics in America. 25 year olds in the bars, plus or minus five years and 45 year olds, plus or minus 5 or 10 years, who are buying games for the home. They're raising a whole new crop of players because now they're 12 and 15 playing in Dad's rec room and when they're 21, or 19 with a phony ID, they're going to the bar playing our games."

Now, with less games going on location, why should they try to appeal to any other demographic other than the one that buys most of their games? If you want more variety in themes, play on location regularly and encourage others to do the same. Women enjoy playing and socializing on location just as much as men do.
'Kids' is a relative term. Kids under 10 are too young for pinball. Both psychically and mentally. There's no reason to go after kids that young. Young kids enjoy redemption games. Kids 10 and older do fine with pinball.
