I'm all for breast fondling, but it has never occurred to me that it could be used as a form of marketing. Leave it to the hornballs at Tecmo to try it out first.
In the video below, watch as passers-by fondle two protruding breast shapes along a wall in Japan. I love how no one has any issue with a quick caress, save maybe for the lady at seven seconds in. She looks disgusted. The guy at 0:13 looks around first before giving them a squeeze, and several others follow -- even a couple, one on each breast. Look above the installation: there's actually two hands reaching over the top, which suggests a totally different mental image behind the panel.
The only indicator that this perverse ad has anything to do with games is small print in the lower right hand corner of the installation. Ninja Gaiden Sigma 2, it proudly boasts. That's our Tecmo.
