Hooman Nissani – Turning Big Ideas Into Living Game Worlds

From teaching himself programming at the library to leading the development of complex open-world systems, Hooman Nissani has built a career around understanding how games work beneath the surface. His journey reflects a lifelong curiosity about technology, storytelling, and the systems that bring virtual worlds to life.

How a curiosity about games became a career in game development

Many people grow up playing video games. Far fewer grow up wanting to understand how those games are built.

For Hooman Arman Nissani, curiosity about how games worked became the starting point of a career in game development. Today, the Culver City-based developer is known for building complex systems behind modern games, including artificial intelligence behavior, open-world mechanics, and procedural environments.

His career spans multiple studios and projects, from early indie development to leadership roles on major titles and eventually founding his own independent studio, Nissani Interactive.

Looking back, Nissani says the motivation was simple.

“I didn’t just want to play games,” he says. “I wanted to understand the systems behind them.”

Early interest in programming and game design

Nissani was born in Glendale, California, a city just outside Los Angeles. Growing up in the late 1990s and early 2000s, he experienced a generation of games that pushed the boundaries of storytelling and technology.

Titles like The Legend of Zelda: Ocarina of Time, Half-Life, Final Fantasy VII, and StarCraft made a strong impression on him.

But instead of simply playing, he started asking questions.

“What fascinated me was how everything interacted,” he says. “Why does the world respond to the player in certain ways? What systems make that happen?”

By the age of 12, Nissani had already started teaching himself programming through books and tutorials at the Glendale Public Library. His early coding experiments included QBASIC, HTML, JavaScript, and C++.

One of his first projects was a simple 2D platform game.

“I built a small platformer based on places around Los Angeles,” he says. “It had levels inspired by the Santa Monica Pier and Griffith Park.”

The project was simple, but the process gave him a new perspective.

“You start to realize that every part of a game is built piece by piece.”

Studying game systems at UC Irvine

Nissani attended Clark Magnet High School, a technology-focused school in Glendale known for engineering and STEM programs. There he studied computer science, robotics, and digital media.

During his senior year, he designed an educational game that taught physics through puzzles. The project won a regional student competition.

“That was the first time I saw how games could teach people something,” he says.

He later attended the University of California, Irvine, where he earned a Bachelor of Science in Computer Science with a minor in Game Design and Interactive Media.

At UC Irvine, he focused on technical areas that would shape his career. These included game engine architecture, artificial intelligence systems, graphics programming, and procedural generation.

He also joined the university’s Game Developers Club, where students collaborated on experimental projects.

“You quickly learn that building games requires artists, designers, writers, and engineers working together,” he says.

Starting a career in the video game industry

After graduating in 2009, Nissani moved to Santa Monica to pursue work in game development.

He began as a Junior Gameplay Programmer at PixelForge Interactive, where he worked on mobile games and small indie titles. His responsibilities included coding gameplay mechanics, fixing bugs in the game engine, and optimizing performance for different devices.

Those early roles involved a lot of problem-solving.

“Debugging teaches you patience,” he says. “You spend hours trying to understand why a system behaves the way it does.”

The experience helped him develop the technical mindset that would define much of his career.

Building complex systems in major game projects

A major step in Nissani’s career came in 2013, when he joined NovaRealm Studios as a Gameplay Systems Engineer.

There he worked on the open-world RPG Eclipse of Empires, released in 2014.

His contributions included building enemy AI behaviors, creating procedural weather systems, and helping design the game’s skill tree architecture.

“The goal was to make the world react to the player,” he explains. “Weather, AI, and physics systems all had to interact.”

The project helped establish his reputation as a developer skilled in building large interconnected game systems.

In 2017, he became Lead Programmer on the cyberpunk action game Neon Circuit.

Set in a futuristic Los Angeles, the game required detailed urban simulation. Nissani helped develop crowd behavior systems, NPC dialogue logic, and vehicle physics designed for city gameplay.

“You want players to feel like the world exists even when they’re not looking at it,” he says.

Leading development on frontier architects

By 2020, Nissani stepped into the role of Technical Director on the strategy sandbox game Frontier Architects.

The game allowed players to build and manage colonies on distant planets. It relied heavily on procedural terrain generation and autonomous NPC systems.

The design allowed many gameplay outcomes to emerge naturally rather than being scripted.

“For me, the most interesting games are the ones where players create their own stories,” he says.

The title gained attention among strategy players and modding communities for its open-ended systems.

Why Hooman Nissani founded Nissani Interactive

After more than a decade working across studios, Nissani launched Nissani Interactive in 2021.

The Los Angeles-based studio operates with a small distributed team focused on experimental and narrative-driven games.

For Nissani, the move was about exploring new ideas.

“Independent studios can experiment more,” he says. “You can test new mechanics and systems without huge production pipelines.”

Much of the studio’s work explores artificial intelligence-driven characters and adaptive storytelling systems.

The future of AI and procedural worlds in gaming

Looking forward, Nissani believes artificial intelligence and procedural generation will continue to shape the gaming industry.

Instead of static worlds, games may become more responsive and dynamic.

“The future is about systems interacting in ways that developers can’t always predict,” he says. “When a player discovers something unexpected, that’s when a game becomes memorable.”

For Hooman Nissani, the process still begins with the same curiosity he had as a child.

“You start with a question,” he says. “What kind of world can we build, and how will players interact with it?”
