I've never played Among Us. It's just a source of memes to me =P
One of my nephews wanted me to help with something in Minecraft on his Switch and to me looking around with a controller's stick was just far worse than looking around with a mouse.
The button layout was weird to me too, as I play it on PC, but that I could adjust to if needed. Anyway I tried for like a couple minutes to even get my bearings in the Switch version of Minecraft and then just went 'nope, you're on your own'. =P
I'll take the mouse for Minecraft''s camera controls any day of the week lol, much better imo, especially for a game with creepers that like to go kuhboom on you suddenly.
I have a Switch Lite so I can't really comment on connecting it to the TV =P
Handheld is definitely the way to go for consoles though =3
