I love that there is no rhyme or reason to this list in terms of game genres, it is just a diverse list of damn good games.
It really proves that the deck platform is the opposite of a platform like VR where a narrow range of video game genre adaptions work well and most of the time translations to the medium just miss the point or feel clunkier.
People are just playing pc games on their deck, all kinds of pc games, there is no pattern to it other than the limitations of the deck hardware. I really don't think there is any stronger statement about how titanic of a shift the steam deck is in the pc gaming world than this list because it decisively puts to rest any claim that the Steam Deck is a fad or that it only works well for a narrow range of pc games, or that linux will never become popular enough or that barely anybody is ever going to want to try to adapt mouse and keyboard focused games to steamdeck controls.
There is a quiet confidence to this list and it is extremely exciting.
