This type of "party game" is still at it's core objectifying women. They may be generated images but the whole project is aimed at passing judgement on women you would rate as fuckable or not. It's encouraging behaviour that makes women feel uncomfortable or unsafe.
This type of objectifying isn't exclusive to this project. Groups of men will rate and objectify women casually and frequently. I've worked in the trades and have been surrounded by such talk from men. The more normalized this type of behaviour is, the easier it is to consider women as less than human. Feeling like a replaceable tool with no sense of self or sense of worth is dehumanizing.
They could have chosen to base this project on just about anything else in our world. We have animals, nature, technology and so much more to try this kind of thing out on. Yet, what seems like another "tech bro" idea was focused on hyper sexualizing and objectifying women as if they were just another thing for men's entertainment.
Simply, it's gross behaviour. Just because they are generated images does not make it any less gross or acceptable. People are not objects for another person's amusement and we should not encourage such behaviour.
