The Dualsense controller is by definition a game changing feature.

I wouldn’t say it’s a “game changer”, but I also hesitate to call it a gimmick. Complements the games it works for very nicely! For instance, TLoU:Pt1 with its wide range of trigger resistance. Helps make the game far more immersive, as well as giving the player a greater sense of feel with their inputs.
