Video games are often judged by their graphics or story. But the real magic usually happens under the hood. That is where developers build the systems that make worlds feel alive.
Hooman Arman Nissani has spent his career doing exactly that.
The Glendale, California native is a video game developer, game designer, and technical director known for his work on complex game systems, artificial intelligence, and open-world mechanics. Over the past decade, he has worked across multiple studios and projects before launching his own independent studio, Nissani Interactive, in 2021.
His goal is simple but ambitious.
“I want games to feel like living ecosystems,” Nissani says. “The best moments in games are the ones the developers didn’t script.”
Early Curiosity: From Arcade Games to Programming
Nissani’s path into the gaming industry started early.
He grew up in Glendale, just outside Los Angeles, in a household where education and creativity were strongly encouraged. As a child in the late 1990s, he became fascinated with the games that defined that era.
Titles like The Legend of Zelda: Ocarina of Time, Half-Life, Final Fantasy VII, and StarCraft left a strong impression on him.
But playing games was only part of the experience.
“What fascinated me most was not just playing,” he recalls. “I wanted to understand how the game actually worked.”
By age 12, he was teaching himself programming using books and tutorials from the Glendale Public Library. His first languages included QBASIC, HTML, JavaScript, and C++.
One of his earliest projects was a simple 2D platform game inspired by the Santa Monica Pier and Griffith Park.
“I remember trying to recreate places I knew,” he says. “Even back then I was thinking about how environments shape gameplay.”
Studying Computer Science and Game Design at UC Irvine
Nissani attended Clark Magnet High School in Glendale, a school known for its engineering and technology programs. There he focused on computer science, robotics, and digital media.
During his senior year, he won a regional student competition for creating an educational game that taught physics concepts through interactive puzzles.
The experience reinforced his interest in interactive systems.
After high school, he enrolled at the University of California, Irvine, earning a Bachelor of Science in Computer Science with a minor in Game Design and Interactive Media.
At UC Irvine, he focused on subjects that would later 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 small independent projects.
“That environment was important,” he says. “You learn quickly that game development is deeply collaborative.”
Breaking Into the Gaming Industry
After graduating in 2009, Nissani moved to Santa Monica, where many game studios operate.
He began working as a Junior Gameplay Programmer at PixelForge Interactive, contributing to mobile and indie PC titles.
The role gave him hands-on experience writing gameplay mechanics, debugging game engines, and optimizing performance for smaller devices.
Those early years shaped his technical approach.
“You spend a lot of time fixing problems,” he says. “Debugging teaches you how complex systems actually behave.”
Eclipse of Empires and a Breakthrough Project
Nissani’s career took a major step forward in 2013 when he joined NovaRealm Studios as a Gameplay Systems Engineer.
There he worked on the open-world RPG Eclipse of Empires, which launched in 2014.
His responsibilities included designing enemy AI behaviors, building procedural weather systems, and creating parts of the game’s player skill tree architecture.
He also worked on environmental physics interactions.
“The goal was to create a world that reacts to the player,” Nissani says. “Weather, AI, and physics all had to talk to each other.”
The game’s success raised his profile inside the industry and opened the door to larger technical leadership roles.
From Lead Programmer to Technical Director
In 2017, Nissani became Lead Programmer on the cyberpunk action game Neon Circuit.
The game was set in a futuristic version of Los Angeles and required complex urban simulation systems.
His work included crowd simulation, NPC dialogue AI, and vehicle physics designed for dense city gameplay.
Three years later, he served as Technical Director on the strategy sandbox game Frontier Architects.
The project pushed deeper into simulation systems.
Players could build colonies on distant planets using procedural terrain generation and autonomous NPC colony management.
“These kinds of games are about systems interacting,” he says. “When players discover unexpected outcomes, that’s when a game becomes memorable.”
Founding Nissani Interactive
In 2021, Nissani founded his own studio, Nissani Interactive, based in Los Angeles.
The company operates with a small distributed team of developers, artists, and writers.
The studio focuses on narrative-driven indie games and experimental AI-driven NPC behavior.
For Nissani, the move to independence was about creative flexibility.
“Smaller teams can take bigger risks,” he says. “You can explore ideas that might not fit inside a large studio pipeline.”
Much of his current work explores adaptive storytelling and AI-generated characters.
The Future of AI-Driven Game Worlds
Looking ahead, Nissani believes the gaming industry is entering a new phase.
Advances in artificial intelligence and procedural generation are changing how interactive worlds are built.
Instead of scripted experiences, games may evolve into dynamic environments that respond continuously to players.
“The future of gaming is systems that learn and adapt,” he says. “Stories won’t always be written ahead of time. They will emerge from how players interact with the world.”
For developers like Hooman Nissani, that future is already taking shape inside the code.
