Nintendo on a mission to block YouTube videos showing Steam Deck emulating games
In theory, Nintendo does not need to worry about potential competition in the form of Steam Deck. The Nintendo Switch console is used by more than a hundred million users and one of the reasons for this is that the device itself is very easy to use. Steam Deck has yet to attract users, and all Deck owners agree that it is a device for enthusiasts who want total control over their gaming device.
However, Nintendo is well aware that Steam Deck exists. This is evidenced by their new foray into YouTube, where they block all videos showing Steam Deck emulating games for Nintendo consoles. By the way - it emulates them very well, so in some cases, the games perform better than on Nintendo's native hardware, which is not much cheaper than the basic Steam Deck model.
Legally speaking, emulation as such is not illegal if the player contains a copy of the game he is emulating. However, as is often associated with piracy, Nintendo has a strong stance on this. Sony and Microsoft are not making similar moves so far, but the fact is that there are no emulators for their current consoles on which they sell their games. At Nintendo, the case is different, and they do not like the fact that the emulator on Steam Deck is very easy to get. As the device comes with a Linux distribution installed, you can easily find all the important emulators in the application store, which are also free to download.
