Pornstar battle 2, at first glance thought was just a match the pair or solitaire type game, but turns out it's more like top trumps with a good amount of content and at harder difficulties you have to actually think more than just put down your favourite actress you want to see
As with most things in small doses and used in a sensible manner it's fine, but unfortunately we live in a world of mass production/consumption so it's getting overused and used to cut corners (mainly taking jobs from actual artists)
I'm not against AI art exactly...it's just mostly when it's used the plot is almost always identicle to all of games using AI art, for example the endless list of NTR 'phone' games. Great idea when it was first done but as with AI art it's just overused and lazily done that i have no interest in...
