The only thing I have ever played, aside from racing/driving games, that really made use of the analog nature of the triggers, was Metal Gear Solid. Squeezing the trigger really lightly just held the gun up. Holding it a little harder activated the laser sight. Pulling it all the way fired your gun. That game made use of every feature of the controller back in the day, which was also one of the only games I’ve ever played that used Playstation’s pressure sensitive face buttons. AFAIK, they don’t even have pressure sensitivity anymore, like the original DualShock controller did. I pretty much never see the analogue triggers used beyond a basic 1/0 switch outside games with vehicles (and sometimes not even those). There’s no degrees of actuation unless using them to accelerate and brake. And I’m not sure what else you could really use them for besides feeling like an actual trigger when using a gun in the game (which the adaptive trigger system does really well).
