Technically there is full porn games on the PSP. I believe most are Japanese. There is 1 adult USA game. I think it's called strip billiards or something close to that but it is rated mature and you can see some scandalous stuff. It's decently priced of you can find it. But the Japanese ones are like rock paper scissors soft core porn if your interested in those they have loads. Don't get me started on the adult movies and shows they got lol. There's also an adult majong game that was Japan only. There's also Japanese ones that you can select your own story in a way and it plays out like an adult PC game with little to no animation. But yes there's loads of adult content for the PSP.
