I like the idea of Trophies/Achievements, nice way to show some kool accomplishments you've achieved. That being said a lot of people take it too seriously to the point where I've seen individuals say: "Game doesn't even have trophies, why bother playing it". As for myself, if I like the game I may try to get all the trophies as an extra challenge. Often it ends up being a good time, if it isn't I don't stress over it.
