Inspiration
I’ve always loved tycoon-style games like Roblox Tycoon and Fortnite Creative Tycoon. But I wanted to create something more immersive, relaxing, and personal — where you don’t just click to earn, you actually feel your world growing around you. That’s how MEGA MANSION TYCOON was born: a mix between a builder, a social hangout, and a 3D luxury fantasy. It’s a relaxing and satisfying tycoon experience where you can truly live the billionaire villa life.
What it does
You start on a flat concrete plot in the middle of a paradise island 🌴. Every second, you earn 💵 that you can reinvest to build, expand, and upgrade your dream villa. Each upgrade unlocks new areas — pool, garage, rooftop, helipad, lounge, and more. You can play solo or with friends: send money, help each other build faster, or simply relax together and enjoy the view. It’s a relaxing, social, and satisfying tycoon where you can live your billionaire fantasy.
How we built it
MEGA MANSION TYCOON was built with a mix of handcrafted 3D modeling, creative scripting, and AI-assisted tools.
🧩 90% of the assets, models, and structures were fully handmade — modeled and assembled in Blender or directly with Horizon’s native shape tools.
🤖 9% of the work involved GenAI assistance, mainly for ambient sound effects, texture ideas, and concept inspiration for certain props and materials.
🎭 1% of the elements come from the public Horizon asset library (fun decorative props and interactive objects).
Every object, light, and layout was manually adjusted to ensure high performance and visual harmony. The goal was to achieve the perfect balance between aesthetic quality and smooth gameplay — all within Horizon’s creative limits.
Challenges we ran into
Keeping performance stable with detailed, high-poly designs.
Blending AI-generated sounds naturally with the environment’s atmosphere.
Achieving a satisfying building loop without overloading players with complexity.
Making the environment feel alive and relaxing, even when idle.
Accomplishments that we're proud of
Created an entire luxury island environment from scratch 🏝️
Built a fully functional tycoon progression system (income, upgrades, co-op money transfer).
Designed a consistent art direction — modern, clean, and luxurious.
Combined manual modeling and GenAI in a creative, seamless way.
Turned a blank world into a living, evolving experience — completely playable and immersive.
What we learned
This project pushed my understanding of 3D world-building, optimization, and player experience design. I learned how to merge artistic creation and technical scripting, and how small details — lighting, props, or sounds — completely change how players feel. It also proved how GenAI tools can boost creativity without replacing craftsmanship — just by speeding up inspiration and testing ideas.
What's next for MEGA MANSION TYCOON
