Because they make a lot of money.

Would you be happier if it were paid DLC? It’s more fitting as a mod anyway, since the whole thing was very on-the-rails.

Listen, I love my Steam Deck, but it isn’t a reasonable replacement for heavy Switch users, like this guy and his family. It’s not exactly a high-spec’d machine and as a result, in my experience, none of the Switch games play at their original FPS on the Deck. Some are so bad that they are unplayable. Online play is going to be, at best, limited and far more difficult to manage. Heck, setting it up in general for kids that probably just want to play the damn games is going to be more annoying. The worst part would be listening to, “Dad, why can’t we just buy a Switch?” a thousand times.
