Recently set up EmuDeck, so the real question is what am I not playing? Jokes aside, currently taking a break from the Deck for D4 (wanted better graphics and smoother framerate so I went with PS5). Will probably grab it on PC when there's a sale just to be able to play it on the go... well, wherever wifi is available.
Other than that it's been mostly "Fuck Around With Tweaking the OS and Settings to Get Games Just Right and Then Never Actually Play Them" Simulator. Windows 11 runs surprisingly smooth off of just a MicroSD card.
