Played dishonored 1 and 2 earlier this year on my steam deck and they played great. Also FYI - month ago I grabbed expedition 33 and started it - as someone who loved ff turn based games and baldur’s gate and turn based pathfinder, I found it extremely boring. Quit playing after forcing myself to continue for 15 hours thinking it would get better.
Probably just me, but maybe look into it more before making the buy.
