Well... If you see doki doki literature club as porn, wtf??

Less mockingly, I also appreciated tank dating simulator. It's not a porn game but makes fun of them, all the "girls" are actually historical tanks and their friends/enemies as well as features/issues are historically accurate as best as I could tell. For example the French girl/tank keeps running into people(yes literally running into them) because the French tank she is modeled after had many issues with it braking system.

Arches isn't pornographic, but it can still hurt you in other ways.
