i’m not a super prolific gamer by any means, but I have 30ish games on PS4, a good mix of indies and triple As, and basically none of them seem to use to touchpad in a way where you couldn’t just use a normal button or a normal button plus an analog stick.
I’m blanking on names but I have played some games where different swipe gestures on the touchpad have been meaningful which I felt like were good uses.
