The Steam Deck came to completely replace my gaming on PC precisely because of this, but mouse+keyboard type games are a mixed bag of experiences... depends a lot on each game.

This one seems to run great, touch screen probably helps a lot. Only complaints seem to be small text on screen:

I also wasn't able to adapt to first person shooters, after a life of playing with mouse, it is almost impossible for me to not feel that gamepad controls are clunky.
