I don't necessarily find the process of signing in (to online accounts) on gaming consoles as convenient — it takes a while to create the account, type in your secure ≥16-character password and multi-factor authentication passphrase, and I'd rather to go without a public profile where my gaming activity may be shared. I however will connect my Switch to the internet in order to receive updates.
I don't plan to use the Eshop due to concerns of the lifetime of the service, I buy my games in physical form. I won't pay for the online subscription either since I can't easily use a wired connection and my wireless network has delay.
Will I be able to access the basic (i.e. "free") online features in games? Are there any other concerns I should be aware of?
