Ok so Special NPC’s from what I can tell. Some you have to finish their story to get any where with. Which hints will help with. Some don’t have a story and you just gotta take ‘em on dates and such until they say yes. Professors I hope sombody corrects me if I’m wrong. But I don’t think you ever truly get a relationship with. But you can flirt with them, meet them outside of school, get their numbers, and take them on a few date styles. Even sometimes booty call them I believe.
And I agree with you I would love smoking to be an added thing you can do like outside a building or in the mall. If you purchase cigarettes or at least Weed in the shops. I mean you can randomly get smoke joint events in the mall. So changing it so you can carry your own and smoke it could be fun. And like you said there could be events based around it. Like a character bumming a cig or asking for a light. Maybe even since it’s a porn game. Somebody who can’t afford their smokes, offering a “Favour” for a smoke. Ooh even have the group hang outs have an option to bring out your weed to get some alternate events.
though this might take allot of work for the poor game dev. It could be cool as hell. And depending on how in-depth they wanna get, they could keep things as they are now. Where intoxication is for both booze and weed. Or they could add High and Intoxicated as two separate things. And allow for cross fading.
