Pretty much, the presentation and music also adds to nostalgia especially if you grew up playing the GBA era like I did.
Joi is the name of the game (Jerk off instructions) and that's something me and a lot of others are into. If it's not your thing then you at least didn't put any money down on trying a new experience but I hope you did enjoi your time playing regardless.
Side Note: I plan to do more with this concept in the future and add more interaction + responsive elements but I never want to pump these games out so that each one feels unique like your interacting with a different character IN character and not just interacting with a popular character with generic writing scripts.
