Meh, I'd give the Platinum Trophy in Tomb Raider: Underworld a 7/10. You can easily get most the trophies your first playthrough. After you finish the game, you can just go back to each level and collect all the treasures and relics you missed in each level. I think the most difficult trophy for me was beating the game on the Hardest settings. Still, this game was very short and simple.
