Suggestion:
New Location: Neon Row -> "Starmaker Booth"
Here you can have random encounter with the other stars from Starmaker.
Once Anna progress in the story line, she will also be able to be encountered, wearing her Bimbo Outfit.
Possibility for alternating outfits:
Slutty Outfit, Chinese Dres, Hucow Outfit, Goth Slut, Etc.
Possible actions:
Grope her (Anna)
Encourage her to do fan-service (Anna)
Grope other girls.
Random chatter.
Meet and Greet.
Go to VIP Room - with another Star, or with Anna alone, or with Anna and a fan.
Possible minigame:
Camera - take pictures at the right time
sneak peek
Could be, yeah.
It does add to end-game content, and it can be expanded upon to add some horizontal progression.
I don't know anything of game development, but you could cut VIP room, alternating outfits, and minigames from that, and I think it would still add meaningful content.
I feel there is room to integrate the in-game Starmaker platform further into the current version of the game, and I hope some of this could be part of the 2.0 release. The other Stars have been surprisingly absent, so would be nice to actually meet them at some point.
