Wow, wtf? So far Sony’s been good to the Deck, and while I don’t mind the psn requirement (when it’s upfront!) this seems either dumb or somewhat of a slip up. Hopefully someone will fix this (either Sony with an update to lose the Windows dependencies, or Valve with Proton sorcery). It is after all in Sony’s best interests to not encourage people to use systems from their competitors, so supporting Linux would make sense…
