StreetPass was a neat feature on 3DS. It was great at encouraging one to take advantage of the 3DS's portability.

That’s one I could see coming back. It was a fun idea and can be worked into casual games fairly easily - as was demonstrated on 3DS.

I fully thought that the connecting bit between the two sides of the controller would be gone by now or at least detachable like the wiimote and nunchucks/joy con's. Why do we need that? So we can be uncomfortable. I thought the future of the PS controllers would be what they are using for PSVR 2. Perfect design.

Because it sucks for anything not VR. It was awkward on Wii

Black and white/color switches
Channel 3/4 switches
Light guns that look real. The Odysssy doesn’t fuck around!

No, I don't mean the motion controls, just the design where both sides are detached and you can stretch out your arms while still holding the controller. 

I think there may be just a dozen of you who want that. Controllers are fine as they are... except for needing Turbo buttons.

Oh and bring back start/select

People don't know what they want until you force it on them. If Sony made the Dual sense detachable in the middle I tell ya, lives would be improved. You could be doing jumping Jack's while gaming at the same time or just go flat out dead mode. Any position, Leynos, you could scratch your back and not have to pause the game or stop playing, You could... okay that's all I got. It's holding our species back from becoming one with the technology. 

Yeah, that's why Kinect saved Xbox and the brand is the healthiest it's ever been, and why Wii U outsold Wii right? lol

-Free online for paid games.
-AV Component Support: Wii U was the last new console released as far as I'm aware to support this without an adapter.
-Startup sequences: Xbox One has one, but PS4 didn't (not really), Switch doesn't, and PS5 and Series X/S are too fast to need them.
-Support for music, video, and image files (jailbreaking doesn't count)
-Themes: Switch only can switch between black and white, and PS5 and Series X/S don't have them.
-Near-universal support for offline physical games. There are some notable games on Switch, PS4, PS5, Xbox One and Series X that require internet downloads to play even if you have the physical game.
