It's interesting to me how so many people disliked the Dream Story. I rather liked it. It did a lot of different things with the characters. Most games are going to follow the manga story but…...I know the One Piece story and I'm sure most of the players do too. I've been reading it for many years. So them taking liberties and playing around with story events and etc was fun to me. As said before, it'll get pretty stale if every single game is a re-telling of the main story just with more arcs and characters.
I enyojed the Dream Story twoo, it was an intressting Point but I can understand the People who want a Canon cause most latly OP Games are What Ifs, SGBX the latest example. After PW 1 only Romance Dawn was Canon. I hope Dream Log is kinda What if for PW 3.
