Do you play the same games together often? In that case unless it is a couch co-op game (some are) you would need a second switch with the same game.
You can have multiple profiles on a switch and can share games between profiles on that switch. If it’s physical you can just play that game on any switch on any profile (just whoever has the cartridge). If it’s digital, if you buy it on the primary profile of a certain switch (make sure you do this) then all the other profiles on that switch can play that game too. If you want to share digital games between different switches it’s more complicated, but it requires cloud syncing and some other shenanigans I couldn’t explain.
They are all portable but you might be talking about the switch light which doesn’t have removable controllers. If you have a tv one for everyone, the you either need the controllers from the other switches or extra controllers (joy con style or normal controller style) to play together. Some games can be a lot of fun to play on the tv together. Check how many people a game can play.
I hope I answers some of your questions.
No, the implication is that when a major website reviews a game “best of the year” often means that it has had a huge effect on the gaming society. Instead it reads like a like a single person’s opinion piece, which makes me feel like I am being tricked into believing this is already a an established amazing game that I should already have known about. I personally am a little more skeptical about a single opinion that I can’t verify than something that a lot more people have played. That is my point. I have no problem believing that they believe this is a great game.
How do you get that setup? My steamed is mostly stock now.
