Rise of the Ronin

The platinum - pops the instant every other trophy is done. With nothing missable and the whole game replayable through the Testament of the Soul, it's purely a matter of clearing the list. Once the story's behind you, the two completion golds (Friendly Neighborhood Ronin and Social Climber) plus the collectible sweeps (Cats Over All, Sightseer) are the bulk of what's left.
