Absolutely zero. They don’t give you anything of substance other than a dopamine hit if you care about it. Many of them are totally arbitrary. Kill x number of enemies in a single play through. I care about getting things in the actual game. Like weapons, armor, secret characters, unlocking powerful abilities, beating secret bosses. They were just as satisfying for me before trophies than they were after. I’m not going to play a game I’ve done everything in 20 more hours just to do arbitrary stuff that makes a little notification pop up on my screen. I’d rather just start a new game.
And honestly, along with online gameplay, trophies are part of the reason cheat devices don’t really exist much anymore, which I can’t stand because cheat devices brought me way more enjoyment than trophies or achievements ever did. I loved going back into games after I beat them with infinite ammo, debug rooms, etc and mess around. It was a ton of fun.
