When I need to focus, I have an entire playlist of Weather Channel type jazz. It’s energetic enough to give me baseline stimulation but not so much to turn on party mode, and being instrumental means it doesn’t steal the attention of the words part of my brain and wreck my ability to actually do work.
Sony made some significant changes between the PS4 and PS5 controllers. I don’t know the details beyond the dynamic resistance triggers, but if you buy a controller board to make your own fightstick, it’ll work with everything up through PS4 and then you need an additional daughter-board to make it work with the PS5.
