That's not the case with most Switch games, unless the creators are cheap and the game exceeds 16GB. Even when that's the case, though, the front cover of the game has a banner that says "An internet connection and microSD card are required to play this game"Or the ROM chip is 8MB just to prompt for an update, and downloads the entire game digitally. Like a download token. Doesn't seen unfeesable, does it? Bethesda and other companies are starting to pull this bullshit, so it wouldn't surprise me.
