The first Phantasy Star revolutionary 3D dungeons caused players to feel sick due to smooth animation, a surprising challenge for its time.
The Early Genius Behind Phantasy Star
Back in the day, the name Yuji Naka was synonymous with innovation and talent at Sega. Long before controversies clouded his reputation, Naka was a shining star in the gaming world, responsible for several hit projects. One of his earliest and most iconic contributions was the legendary 1987 RPG Phantasy Star for the Sega Master System.

A Leap Into 3D Dungeons
Last month, Shmuplations released a translated 2000 interview with Naka, where he reminisced about the creation of this cult classic on the 8-bit console. The standout feature? The revolutionary first-person 3D dungeons with incredibly smooth animation—something unheard of back then.
Naka recalled:
“After discovering Wizardry, a 1981 RPG, I wanted to create the world’s first game with truly smooth 3D dungeons. It was crucial that when you turned in the labyrinth, the image wouldn’t just snap to a new position but would rotate beautifully and fluidly.”
This smooth rotation was a technical marvel for its time, setting Phantasy Star apart from other role-playing games.
Faster Prototype and Unexpected Side Effects


Interestingly, the initial prototype ran much faster than the final product. Naka proudly showed off this speed to his colleagues, who unfortunately reacted with pale faces and complaints about feeling nauseous.
“It was funny because the original prototype was much faster. You could literally fly through the caves like a ride! I proudly demonstrated this speed to my colleagues, but they just turned pale and complained about nausea.”
This was Naka’s first brush with the motion sickness problem that would later plague gamers in titles like Doom and GoldenEye 007 during the 1990s.
Technical Limits Save the Day
Ironically, it wasn’t a design fix that solved the nausea issue but rather a technical compromise:
“Our smooth scrolling consumed 3 MB of the available 4 MB! If we kept it up, we simply wouldn’t fit the game on the cartridge. We had to implement data compression with on-the-fly decompression, which slowed movement down by 4-5 times. But strangely, this forced slowness prevented players from feeling sick, and in the end, everyone was happy.”
The limitation of hardware forced the developers to slow down the rotation speed, which in turn eased the motion sickness that early players experienced.
Legacy Without the 3D Mazes
Phantasy Star went on to spawn several sequels, but none inherited the original’s signature first-person 3D dungeon style. The pioneering smooth animation of dungeons remains a unique highlight of the first game, remembered fondly by fans and historians alike.


Phantasy Star’s first-person dungeons were an ambitious step for their time, blending technical innovation with gameplay challenges. Have you ever experienced motion sickness from a game’s graphics or movement? How do you think game developers today handle these issues?
- What inspired Yuji Naka to develop smooth 3D dungeons in Phantasy Star?
Yuji Naka was inspired by the 1981 RPG Wizardry and aimed to create the first game with genuinely smooth 3D dungeon rotation rather than snap transitions. - Why did players feel sick playing the original Phantasy Star prototype?
The prototype’s fast, smooth rotation caused motion sickness, as the visuals moved too quickly without buffering, which was too intense for some players. - How was the nausea problem in Phantasy Star eventually resolved?
The developers slowed down the rotation by implementing data compression and on-the-fly decompression, which unintentionally reduced motion sickness symptoms. - Did any Phantasy Star sequels continue the smooth 3D dungeon style?
No, none of the sequels maintained the first-person 3D labyrinth style that the original was famous for. - What hardware limitation influenced the final speed of the dungeons?
The Sega Master System’s cartridge memory limit forced the team to compress data, which slowed dungeon rotation and helped prevent nausea.
