I'm pleasantly surprised with how well Grim Dawn and Rimworld play on the deck, tweaked both a bit for personal preferences but actually solid experience. I did cities skylines and ksp on the og steam controller, I can't get into trackpad as trackball though on the steamdeck for whatever reason, did that with the steam controller for warframe, was great to be able to turn quickly on a controller.

No trackpad really would be a non starter to me, just adds so much flexibility, and the haptics do totally work for me.
