- Almost every first-party multiplayer Nintendo game on the Switch that I know of has offline local multiplayer. The only exception which comes to mind is Splatoon.
- The Switch has a cartridge slot, and leaks suggest the Switch 2 will too.
- And you can connect two (possibly more with a hub) Pro controllers with a true wired connection: https://en-americas-support.nintendo.com/app/answers/detail/...
Fingers crossed that the Switch 2 maintains this pattern.
It does, but it's hidden behind an unlisted button combination (Zl + Zr + L3 for Splat 3) and every player needs their own console and copy of the game: https://splatoonwiki.org/wiki/The_Shoal#LAN_Play
I am a little disappointed they don't have anything like the DS's download play feature though.
- Battery life isn’t really a problem on full-sized controllers (and the failure modes are “walk the dog around the block while it charges enough for a couple-hour session” or “it becomes a wired controller for a few minutes”) including the Nintendo ones, just the damn joy-cons. Those do suck, but the basic idea of wireless controllers has proven to be really good, not like the old Wave Bird days.
- The Switch is easily the best local multiplayer modern console AFAIK, including lots and lots of co-op options.
Many games were not ported to it because it used a cartridge that couldn't hold near the data of a CD ROM like its peers.
The controller was amazing though.
