Hello there,
saying the content is limited on this game when its actually a lot makes me think you haven't played it, or simply haven't interacted with characters. Your example alone of the beach of "cannot do a thing" is already wrong when there's multiple characters with scenes there.
Instead of a phone to call the girls to have sex, the world feels more alive because you find them doing their own thing, they are not "sluts" in the matter of the word, Anna while even on slut path can be considered slutty, and will depend more on what the player wants her to do.
The outdoor call system could see more to it, but its main concept was more risqué pics outside.
