The one thing that I feel can hurt reviews are forcing dated motion control as the only way to do anything. But I hear MM is working on entirely new control scheme without motion control so hopefully that will be ready soon.Really excited for Dreams, but I'm predicting 86-88 meta at the end of the day. I just don't see it having a broad enough appeal for the wide range of reviewers.
As for the creation aspect, most reviewer probably won't grasp all the depth and complexity the tool provide so they will probably review it based on potential from what the community can make. Which we can already see, it's pretty amazing. So I believe most reviewer will rate it very highly
