If you are an old Nintendo fan, you must also be very pleased to experience the Jedi counterattack and the popularization of Chinese in this generation of switch. But Nintendo, which is busy with change in this generation, has actually compromised and abandoned many of the designs that players talked about before. Now that Nintendo's future plans are in full swing and a new generation is coming, there may be more new and interesting designs, and many may return. 
Local connection. Players who have played Pokémon Sword & Shield must have noticed that whenever you open this game, there will be an extra L on the wifi icon on the desktop, which actually means local connection. So why does opening Sword & Shield automatically enter local mode? This is the game in order to search for other players in the local area, when there are other players who are also playing a single-player game, two people can retrieve each other without additional operations. This feature has been available since 3D games in Pokémon XY, allowing players to see nearby players on the lower screen without having to do so. But the Switch, as a home console in Nintendo's eyes, is also very important for continuous networking, so other games will not switch to local as soon as they are opened. Therefore, the follow-up "Arceus" and "Vermilion" did not continue this function. 
Also taking advantage of a similar feature is the teleportation of 3DS, or what many players call it, Rub Shoulders . As the name suggests, this is a feature that allows players who pass by to exchange information without feeling it. When a player puts the 3DS in the bag or pocket and goes out, if there happens to be a 3DS player nearby, the two 3DS will automatically exchange their business cards or game data through local wireless transmission. Whenever a player passes by, the 3DS network indicator will start flashing green. At that time, many gamers would have been extremely excited to see this green color, especially since the domestic Nintendo player base was far from being as large as it is today. 
After collecting business cards by rubbing shoulders, you can unlock various gadgets at MII Square, which is very rewarding. And games like Mario Kart can even swap car shadows. In those days, when many players participated in comic conventions, game exhibitions and other activities, they would open their 3DS, put the lid of the box in their bags on standby, and turn it out from time to time to see if the green light was on. Even today, when I went to Hong Kong to participate in Nintendo Live at the end of last year, I was still able to wipe players with the same 3DS, and I can't help but regret the absence of this feature from the Switch again. 
Multi-screen linkage. In the past, although there were many creative games on handhelds, in fact, the main position of the fight was still on home consoles, or the game quality and volume of home console platforms, which were often higher than those of handhelds. The birth of the switch put an end to all this, allowing players to enjoy the quality of the game even on the handheld, but it also made many of the interactive gameplay of large and small screens in the past obsolete by the times. In the battle screen of "Pokémon Red, Green, Blue and Yellow", Pokémon are all large pixels. Therefore, in order to make up for this regret and show the thrill of Pokémon battles, N64's "Pokémon Arena" has added a function of linkage with GB. Just insert the GB Pokémon cartridge into the N64 controller's dedicated expansion to read the teams in the cartridge in Arena and let them fight in 3D on a large screen! This tradition continued to the later NDS's "Zhen Diamond", which can be wirelessly linked with Wii's "Battle Revolution", and at the same time as fighting on NDS, it can be used to ** 3D battle pictures on big TVs. It wasn't until the 3DS era that Pokémon all owned 3D models that this tradition was canceled. 
In addition to this way of linking the large and small screens between handheld games and home console games, there used to be a way to use handheld games as home consoles to expand the screen. For example, in NGC's The Legend of Zelda: Rhythm of the Wind, it is possible to obtain a device that resembles a GBA. When you connect the GBA to a dedicated NGC cable, you can use the GBA as an extended small screen to display maps and other content from Rhythm of the Wind. 
Of course, there is also a Wiiu that natively comes with a handheld handle, in fact, its pad is a simple wireless screen, allowing Wiiu to transmit the picture. This standard dual-screen design is not used by most games, but it has also given birth to asymmetrical multiplayer party games with strong gameplay such as "Nintendoland", as well as super immersive titles such as "The Witch of the Crow". In fact, it is completely possible to make multi-screen interaction between multiple switches, and even in works such as "World Games 51" and "Mario Party", there is a way to splice multiple switch screens, which can be regarded as a continuation and innovation of this kind of design. 
Microphone. What was Nintendo's first game console with a microphone? Not N64, not NDS, but. fc！One of the 2P controllers that comes with the FC has a microphone that can interact with some games. For example, in the original "The Legend of Zelda", there were monsters that required the player to shout loudly to kill, and although yelling while playing the game sounds a bit silly, this kind of gameplay is really interesting and eye-catching. 
Later, in the N64 era, Lao Ren released a film called "Hello! Pikachu", the biggest selling point of this game is the voice interaction. Players can purchase a N64 microphone with the game to "communicate" with Pikachu on the TV screen. That is, since the N64 era, including NGC and Wii later, Nintendo has launched dedicated microphone peripherals. In NGC's Mario Party, players can answer test questions with their voice; In Wii, players can communicate through a microphone. (On the right side of the picture below is the Wii's microphone).
With the NDS generation of handhelds equipped with microphones as standard, there are many games that make use of microphone functions. For example, in "Nintin Dog", you can let the dog learn voice commands, and in "Zelda", you can blow air into the screen to blow out the flames. In the 3DS and Wiiu generations, handheld and home phones are equipped with microphones as standard. However, to the switch, it was cut instead.,Although you can also connect an external microphone.,But it's basically limited to game voice and singing games.,No one uses the microphone as a way to play in the switch game anymore.。 
Game linkage. If you've played Switch's Sprague 2, you'll remember that there were many crossover festivals born in this game, including the critically acclaimed Sanrio crossover, McDonald's crossover, and more. But when it came to "Sprague 3", the linkage not only decreased a lot, but even the quality also declined, even the Zelda linkage failed to reproduce the glory of the 2nd generation period. Also experiencing this problem is Animal Crossing. The only crossover for NS's Gathering Forest was Mario, but for 3DS's Come On! In Animal Crossing, there are not only Mario, but also a series of high-praise linkage content such as Zelda and Spra, and even the mobile game version that has been operated so far has a very good quality Spra Escape linkage.
Not only the first party, but also the previous 3D Monster Hunter crossover is also very rich. At that time, as a 3DS exclusive game, "Monster Hunter 4" and "Monster Hunter 4G" had a lot of Nintendo's first-party IP collaborations, including collaborations with works such as "Kinemori" and "Zelda". However, in today's "Monster Hunter Rise", there is nothing. And the lack of this linkage should not be that Capcom doesn't want to engage in it, because like "Monster Hunter World", there is a linkage content of Sony's first-party masterpiece "Horizon", and there is a high probability that Nintendo is unwilling to do it in "Rise". I hope that with the smooth transition of the Switch generation, Lao Ren can put down the wariness of the past few years and bring more linkage between IPs.
Special hardware expansion.
In the past, many home computers often had special hardware expansion interfaces, and even handheld computers could expand hardware functions through cartridges. For example, the bottom of the NGC can be expanded with a network card module and a GBA module, while the GBA has peripherals such as an e-card reader that can be inserted into the card slot. Even in the NDS era, there is still a way to play by expanding the vibration module and memory module through the GBA card slot.
There are many game cards with special functions, such as the earliest "Pokémon Pinball" with vibration, a variety of GBA games with gravity sensor, the GBA game "Our Sun" with a sunlight sensor, "Pokémon Black & White" with a built-in infrared transceiver, a TV card that allows NDS to receive satellite TV, and even a "Pokémon Typepad" that stuffs a Bluetooth module into the NDS cartridge to connect to a Bluetooth keyboard...Not only are there many games with special hardware, but they all offer a really fun experience.
When the switch was released, although the card slot has its own dust cover design, so that the size of the card is fixed, and the design of the card is difficult to stuff other hardware, but joy-con has opened the minds of many players. Gamers have also imagined that the form of JOY-CON may allow the Switch to derive many different peripherals, such as the NGC layout of JOY-CON, the fishing rod JOY-CON, and the gun trigger JOY-CONLater, many joy-cons with different appearances did appear, but unfortunately they were all traditional handle forms. In addition, there are very few hardware gameplay that can be expanded by the switch. And due to the lack of microphones and cameras that used to be standard with 3DS and Wiiu, and the touch screen is no longer a ready-to-use input method, many interesting interaction methods and gameplay methods are no longer possible on the Switch.
