As someone who just played it, stay way the

away from '14. There are definitely online trophies in it. Without boosting you would have to be REALLY good at the game to get it. Then you would have to play a ton or spend some money and get lucky to get another of the trophies.
You could jump almost 2000 spots in the world rankings just by buying and completing the Sound Shapes DLC then auto-popping on the other 2 platforms. No, I'm not kidding.
