I only had the new 3DS, used it for many years. I messed around with the 3D functionality from time to time during these years but it was never good and never got rid of the two things I described.

If a 3DS was able to pull this off flawlessly

It couldn’t…it was highly dependent on viewing angle, both horizontal and vertical, it was really finicky to play 3D games without the 3D illusion dropping because you didn’t hold the device in the exactly correct position/angle. On top of that, the 3D looked weird like those old holographic 3D stickers you’d get in breakfast cereal and such. It was a fun gimmick, but it really didn’t work all that well.

A giant clusterfk of poorly designed, non-intuitive, frustrating systems that did unexpected things or took too much time to set up

That sounds heavily under engineered, not the other way around.

What does VPN hide that HTTPS can’t hide for media server?

HTTPS Doesn’t hide where the traffic is going, so your ISP will track you going to piracy sites. It also doesn’t protect you against identification when torrenting.

Dude, read the rules #2 says no requesting invites
