Because people want to have "a game" with porn in it. They still want to play Skyrim or Rimworld as it is but just kinky stuff they want to see.
Dedicated porn game developers are mostly not so game developers. They create interactive porn experience, you watch porn but got limited control over it. It's not enough for many people. Modders mostly do not know to make a game or not enough time for it. Making a game is way more then modding and requires a dedicated team with many years of development.
Botn is a pokemon game with breeding. Imagine you can bring your neph to catch wild nephs with some kind of sex game which you can use positions as attacks... Imagine to make it online and let people use their nephs for duels.. Options are limitless for a serious developing team.
DH did not care nobody or his game, at least for many years. Sad..
I know you from another game...but Its kinda ironic I mean Its sad that guys like you have hard start compare to others like DH who just milk as much as he can ppl(I dont blame him ppl who donate him are just dumb as fuck so why dont earn money? I would do the same In his place)
True future of porno games will be when AI get better even now the chat AI are so god damn good even If they are not perfect yet.
Imagine a game like Baldur gate 3 but with AI In It who has acces to the internet information where the AI as you companion would do things dependent on what you write In It when you creat a companion for example "Dark elf outcast warlock who despite everything related to the humans kingdom she Is quite person but the darkness even madness can be seen when she get angry" thats just example right without the kinky/porno things but Imagine when you could write down a whole character including looking/perosnality/sex preference and the AI would act based on the information putting In It.
The only real problem with It now Is the AI memory that often forget about things the more you speak with It the more older information It forgot.
Second problem Is that If the AI would have free acess to the internet someone would had to write down a script for the AI to make sure which information to researche If the game itself dont have information about question of the MC (us) like "do you belive In god" then If the game dont have that Information the AI with the script would research correct information In Internet to give us the anserw as we know AI learn the more you speak with It so the more you spend time In game with you AI companion the more AI become more alike human beings...or dark lady elf
I gusse the best way Is to pack as much information some kinda of data base of races/genders/religions/classes In the game would be good enough the thing with internet Is that If the game Itself would miss a information the AI would just research the information because the game cant contain a whole internet informations.
The last problem Is how fast the AI would react to our actions and question,the best way would be just teach the AI,the AI also would require a stable server In order to gathering information based on our current stage/conversation/actions etc.
