Far too many games seem to know nothing about these things. (In general, I'm not saying anything about this game specifically.)
Not talking about this game!!!! I already stated that the writings in this game is pretty decent, though there could be improvement making Hannah more believable as a teenager.
Yeah, I have a feeling that porn games are made by amateurs and their focus is often spent on art and coding. The writing is actually the hardest part that seems to get the least amount of attention.
Example: 40 year old virgin women: "I know I just met you but lets go upstairs and pop my 40 year old cherry!" This will never happen for 2 reasons. One, because people who make it to 40 who are virgins have something mentally prevents it. It may be religion, or their self worth says they don't deserve it, because anyone can get sex. There is tinder, or hookers or being at the bar at 3am, so everyone has access even if the quality is horrible. Reason two is that I don't see a 40 year old women using the wording of poping her cherry either, that sounds like something a teenager would say, not an older women.
Good writing is important because dictates the speed of reading. Good writing allows the reader to quickly read something and understand it. It's like being on the freeways, vs an unpaved gravel road. Poor writing slows you down and annoys when you have to take time to figure what shit means. The poor grammar and such are speed bumps which really makes reading not enjoyable. If people only care about images then they have pornhub... but they are here for more. Sadly writing well is hard.
