I like the layout of maps as being more "continous" in terms of territories, rather than square territories if that makes sense. Nice seeing more enemies on screen at once. I wonder how they will do this. Will all the stuff in the first one be in this one? (i.e slightly altered albasta, etc) or will they leave it all out? If they just leave it out then there's no excuses for not having Syrup Village, Logue Town, Thriller Bark, redooing Sabaody to include supernovas and fishman island. The problem with the first one was, yes we had Buggy, but we had no Mohji and cabaji, yes we had arlong and hatchi, but not the other two fishman officers, same for mr 1 and mr 4 and the CP9 members left out of enies lobby, and marco, vista and shichibukai in the war. So even if they go back to the arcs already done, there's still a lot that can be added. Saying this, the scenes that were in the game were down well, but they've left a lot to be improved on so this should be a lot better.
I know this is a dynasty warriors style game but we could still do with a versus mode, and even if not this, we could still have major bosses as playable characters (in the first game think buggy, krieg, arlong, hatchi, croc, mr 2, mr 3, kaku, jabra, lucci, magellan, hannybal, minotaurus, admirals, sengoku, pacifista (or rather kuma)). These were all enemies in the game so they had some moves already for them so half the work was done.
There's a lot that could be done, let's see how this goes…
