an explanation of Nintendo Switch 2 GameShare feature, taken from Ask The Developer Vol.16:
In the past, Game Boy Advance and Nintendo DS had a feature called Download Play, where you could send a portion of a game to friends and play together. We looked into the possibility of having this feature on Switch as well. But the data volume of Switch games is so large that it takes a very long time to transfer data, so we had to abandon this idea.
So, we thought that by taking advantage of the Switch 2 console's processing power and using the same streaming technology that Wii U uses to send images from the console to the handheld Wii U GamePad, we could share the gameplay instantly without having to take time to transfer the software. I thought it’d be nice if players could share games instantly and play together competitively or co-operatively. This was another feature I asked Sasaki-san to look into. Achieving it must have been a nightmare. (Laughs)
as this image shows, we'll be able to cast games from a Nintendo Switch 2 to any other systems in the Nintendo Switch family (only NS2 can cast, but all of them can receive)
what I mean by this is: keep your existing Nintendo Switch around. since the Wii U screen casting technology is back, I can imagine the Nintendo Classics for DS library allowing for Dual Screen options.
(and considering the new system supports microphone and camera, even DSi games could join the roster)
as usual, the more options the better! and of course, people with a single system should be able to play the DS games with the two screens being displayed side-by-side.
however, for those wanting a more authentic Dual Screen / Asymmetrical gameplay option, it seems that the Nintendo Switch 2 GameShare feature will allow for exactly that!
which games would you love to see returning?
