Nintendo Built a Special Switch Prototype to Make Game Chat Work on Switch 2

Development on features for Switch 2, which launched in 2025, began around 2020. At that point, Nintendo didn't even know what its next dedicated gaming console would look like, but the company was already thinking about how communication features could work alongside games.

The team wanted communication to be something that worked together with the games instead of simply being another separate feature. As the engineering leader in charge of the project explained, that idea eventually developed into what we now know as Game Chat.

Nintendo started by building a PC prototype and using it to play games while testing voice and video chat.

Through plenty of trial and error, the team quickly realized that sharing the game screen would be a major part of the experience. The PC prototype showed how appealing it could be to talk with someone while also seeing the same game they were playing.

But there was still a problem. A PC couldn't properly recreate what would happen when a game and a chat service were running simultaneously on a dedicated gaming console. Nintendo needed to know whether you could move between the game and chat without interrupting gameplay and whether that transition would actually feel natural.

To test that properly, the developers decided they needed a prototype running on dedicated gaming hardware. Instead of waiting for the next Nintendo console to be ready, the team integrated Game Chat functionality into a development kit based on the Nintendo Switch and built a special prototype.

That created another major problem because the Nintendo Switch had limits on its memory, CPU, and GPU resources. Under a normal configuration, the hardware simply couldn't run all of the Game Chat functions at the same time as a game.

Nintendo therefore made maximum use of resources available only on development equipment and rearranged the system's resource configuration. The result wasn't something that could ever work as a consumer product, but it let the team test the experience they were trying to create.

With that specially configured Switch prototype, Nintendo was finally able to run Game Chat. Being able to experience the idea they had been working toward for the first time gave the team a major sense of accomplishment.

The developers then used the completed prototype to test Game Chat while playing different types of games.

They confirmed that the experience they had seen on the PC wasn't lost when moving to dedicated gaming hardware. Players could switch between games and chat without interrupting gameplay, while playing and chatting also felt like two connected parts of the same experience.

That was important because Nintendo wasn't simply trying to make another voice chat system. The developers imagined a space where people could gather naturally, even without a specific reason. You could play your own game while someone else played theirs, talk when you wanted to, or simply spend time quietly concentrating on your own gameplay.

Nintendo eventually became confident that it could create something resembling a club room as an extension of the game itself. Once the prototype proved that Game Chat had value, development moved into full production. From there, the team repeatedly implemented, tested, and evaluated new ideas.

The developers also explained why Nintendo believed Game Chat was worth pursuing in the first place. The goal was to make online gaming feel more like playing locally with friends, and there was a lot of playtesting involved to get there.

The team started by playing games with voice chat to figure out what makes online gaming feel like playing with friends in person. They quickly found that voice chat alone wasn't enough.

While talking to someone could be fun, people weren't necessarily commenting on what was happening in the game. The game itself could end up being left behind while the conversation became the main focus. Voice chat worked, but it didn't feel much like sitting in the same room and playing together.

That became an early roadblock for Nintendo's developers, so they started experimenting with video calls and other elements. They played games and chatted every day, adding and removing features as they tried to find the right combination to make it feel like everyone was gathered in the same place.

Through that long testing process, Nintendo found that one of the biggest factors in creating that feeling was being able to see and hear the same things. Sharing the game screen with another person seemed to have a major effect on the overall experience.

The developers described the kinds of reactions that happen naturally when you play with someone in the same room. You can yell when an enemy kills you or get hyped when you finally pass a hard stage. Those reactions happen naturally because everyone is experiencing the same thing in the game at the same time.

But if you don't know what the other person is doing, or can't see their reactions, the opposite can happen. Even if you can talk, it's harder to feel like you're together.

Eventually Nintendo distilled the essence of the experience into three things: the ability to talk, seeing the same thing, knowing the other person's reactions. They then turned those ideas into specific features, including voice chat, game screen sharing, and video chat.

Finding those features was only one part of the process. Nintendo also had to make sure people could actually understand how to use them. The developers said they placed a lot of importance on making Game Chat simple enough for anyone to operate. Nintendo wanted it to become a standard Switch 2 feature that even people who don't normally use chat tools could use.

At the same time, the team realized that simply providing the main features wasn't enough. Without some of the functions commonly found in chat tools, Nintendo couldn't provide what it considered a complete chat experience.

The developers therefore started building a user interface around the features they believed were necessary. When they tested it internally, everything appeared to work well. The developers thought they had created something that would do the job.

Then they invited first-time users to try it.

The results were not what Nintendo expected. Those first-time users weren't using the game screen-sharing or video chat features that the developers considered central to the experience. Instead, they were mostly sticking to voice calls.

When Nintendo asked why, users explained that the system had so many features it seemed complicated, so they simply didn't use them. That forced the team to start cutting things back. Nintendo gradually reduced the number of main buttons and repeatedly brought in first-time users to test the interface again. After going through that process, the developers eventually narrowed the main buttons down to just three: the microphone, game screen sharing, and camera.

Those were the features Nintendo considered to be the core of the Game Chat experience.

The team had thought it was already designing the system around the customer experience, but this testing showed them that they needed to simplify it much further. If there were too many features presented at once, first-time users could easily feel like the system was too difficult.

That extra work eventually paid off. Toward the end of development, even people who were using Game Chat for the first time were telling Nintendo that it was easy to use. Some said it reminded them of playing games together at a friend's house.

For the developers, that was the point where they felt they were finally delivering the experience they had originally been aiming for. They believed they had managed to change the impression of Game Chat from something difficult into something that even someone unfamiliar with chat tools could use.

What's particularly interesting about Nintendo's approach is that the company wasn't simply trying to build voice chat because it was an expected feature for a modern gaming console. Instead, the team started by figuring out what it actually wanted online communication to feel like.

The goal was to capture the feeling of playing on the couch with friends when you aren't physically able to be together. You're still playing over the internet, but the experience should feel closer to actually sharing the same space.

That idea became the foundation for Game Chat, and Nintendo spent years working out how to make it function naturally. The company first had to prove that the concept was worth pursuing, then spent even more time testing and refining how people would actually use it.

The timeline also makes Nintendo's other upcoming features more interesting.

The company has recently had patents appear for different ideas, including an event-related system, and Game Chat shows that features like these can potentially be in development for years before they are ready to be revealed or released.

Nintendo started working on Game Chat around 2020, when the company didn't even know exactly what its next console would be. The team had to build a special Switch prototype, push the hardware beyond what would have been possible in a normal consumer configuration, and repeatedly test the concept before it could move into full production.

What eventually arrived on Switch 2 is therefore the result of a much longer development process than the feature itself might suggest. Nintendo wasn't just trying to add another way to talk while playing games. It spent years trying to recreate the simple feeling of sitting next to someone and playing together, even when that person is somewhere else.
