If you haven't got platinum don't buy the DLC as it will add tons of stupid garden tasks. And completing the original tasks 100% will no longer unlock the 100% task trophy. And the garden tasks are endless. I have spent 5 hours already just on the garden tasks and still got 2 (don't know if more is following, I'm on the Japanese Garden task) it will be seriously wasting time. And showing developer's incompetent. Please AWARE!
