titanfall is god tier, others have covered that.
horizon zero dawn i finished recently on my steam deck while travelling, it's great and you basically can pause at any time except in cutscenes, which is a bit annoying when something comes up during important story points.
bioshock i guess is not really my cup of tea, but i didn't find that i was able to put it down and pick it back up. the game overall is quite slow, and all the branching paths means you can easily waste a lot of time.
