After it’s announcement a few weeks back we finally have a trailer showcasing One Piece Romance Dawn. While the trailer isn’t long, it does show some of the earlier fights and a general idea of how it will look. However it does look rather poor even for a PSP.
Sadly not much more is known, so it’s hard to tell how much One Piece will be covered. Considering it’s name it might just be the first 100 chapters, though this could lead to additional titles down the road. However we should get more details soon, since it’s currently set to release this winter.
