I think what he means is other $60 games like God of War, Dead Space remake, and Cyberpunk 2077.
To be fair, as someone who has played Dead Space on the Deck multiple times, I can easily say it’s not the optimal way to play the game. But it WILL run, and I’ve gone through it several times.
The big problem with AAA games on PC is they have separate launchers or online requirements, which sucks for playing on a handheld.
