With AI coming such a long way more and more games are using AI for chatting. Games like Rockstar Life Simulator, and Suck Up! uses this. In these games you can type out what you want to say or use voice, to chat to the character you are talking to , and there are some demos with some game engines that use this.. I think it would be pretty epic if adult games like these could do that. With my experience with stuff like AI Dungeon things can get QUITE interesting and depending on how the characters opinions are of you, depends on your success with making them attracted to you and such. I think seeing this in some of these games would be pretty epic!!! It makes me want to learn some coding to develop something like this. However personally I'm very much a beginner when it comes to development and scripting.. I've dabbled here and there but not made anything too impressive as of yet.
