Aside from dicks the worst common thing in real porn games is the random mix of "models". One chara should always be the same person, not dozens of persons.
I avoid them 100% of the time.
Like mentioned, why not go to the source material to begin with.
Also, since the images are given, the story has to be told around them, or equally likely it seems, have little to do with them at all.
They were good like 25 year ago, when 3d render where very poor in quality. Nowadays with the quality of render beeing almost realistic, is incoherent to make a game using real porn.
Immediately hide/ignore.
Real images kill the entire purpose of the gaming world. Games are not reality, they are supposed to be further from it and thrive on its own aspect and styles.
Some have decent enough writing, if it's pretty much a sex novel with gifs I can get some enjoyment from it. But sandboxy games with random gifs does nothing. I've enjoyed "The company" for example
