LUSTLINE
UTOPIA
Be whoever you want in a city of
sin and second chances.
An adult sandbox RPG where your choices shape who you become. Male or female. Every path optional. Every kink opt-in. Your playthrough looks nothing like anyone else's.
The Game
Not a Visual Novel.
A Living City.
Daily life that matters. Dice rolls where failure is interesting. Systemic depth where the world reacts to who you've become. All in a sandbox where you're not locked into one path.
Nothing Is Forced
Everything Is Possible.
Play as male or female. Date, flirt, fall in love. Dominate or submit. Get feminized - or feminize someone else. Stay vanilla or go deep. Every NPC remembers how you treat them. Build affinity through conversation, gifts, and choices. Content toggles let you shape exactly what kind of game this is.
No Dead Ends
Failed Rolls Open Different Doors.
Dice rolls are flavour, not gatekeepers. Choices come in layers - open options anyone can take, stat-gated options for the prepared, willpower checks that test who you really are. Every check is a fork, not a wall.
Mind States
The Game Reads You Back.
What you wear changes how people treat you. What you keep choosing starts to show - in 38 different ways the game tracks without telling you. Submission. Curiosity. Dark thrill. Exhibitionism. The NPCs notice before you do.
Dress-Up
Dress the Part.
Mix and match outfits, cosmetics, and gear. Dress femme at Victoria Sinner's boutique. Sharp for your café shift. Provocative for the club. What you put on isn't just visual - it changes who approaches you and how.
This is not a game about good choices.
It's a game about your choices.
Characters
Relationships That
Go Somewhere.
Talk to people. Flirt. Give gifts. Push boundaries or respect them. Every NPC tracks how you treat them - and the conversations change to match.
Eva
Your Flatmate
“Four arcs. None of them simple.”
Your flatmate, your lifeline, and the most dangerous person in your apartment. Goth-cute, sharp tongue, beautician who knows transformation inside out. She sees you as her practice model - but Eva's attention is the kind that changes things.
Relationship Paths
Victor
The Unknown
“He bought you a drink you don't remember finishing.”
Powerful, private, and looking at you like he already knows something you don't. He carried you home that night. He keeps showing up. You're not sure what he wants. That's the point.
Relationship Paths
Sera
Pink Street
“Lessons cost money. What she teaches you is worth more.”
She's seen everything. Not easily impressed. You want to impress her anyway. If you want the lewd content without the slow burn, she's the fastest route in - for a price.
Relationship Paths
+ more characters coming. Each with their own schedules, opinions, and ways of getting under your skin.
Features
Built Different.
Plays Different.
Custom engine. No Ren'Py. No Twine. Systems that serve the story - not the other way around.
38 Mind States
Not just a corruption bar. Submission, dominance, feminization, dark thrill, exhibitionism - all interconnected. NPCs respond to your psychological profile. Same scene plays different depending on who you've become.
Dice Checks That Fork, Not Block
Charisma, Endurance, Beauty, Confidence - these shape how the world narrates you. Failed rolls open alternate paths. High stress changes your inner voice. Nothing is a dead end.
Gender-Diverse Content
Male or female MC with body-specific prose. Not a pronoun swap - 330 passages with genuinely different content. Be straight, sissy, domme, lesbian, sub. Same city, different experience.
What You Wear Matters
Mix and match clothing, cosmetics, gear. Dress femme at Victoria Sinner, sharp for your café shift, provocative at the club. Your outfit changes how NPCs treat you.
Time & Routine
Morning, afternoon, evening, night. Rent's due Sunday. Eva's in the kitchen in the morning. NPCs are where they're supposed to be when you show up. The city doesn't wait.
