well I dont know why I never thank of this but I did now so oh well
I think everyone knows that cresent looking island from the Third movie (and for people who dont , watch the movie ) maybe you can make it so that , we can go to a harbor north of sand , and that takes us to cresent Isle , but we find that the place was deserted and full of monsters , we may even have the option to get a quest and venture through the palace till we find the king and the little prince and fight those ninjas , and we can make small rooms that monsters cant reach in the castle , for people to call there MINI-BASE , or for people to regenarte health without the fear of getting attacked by monster the momet you Meditate , and once the quest is finished you may get elegibilty to buy a boost and specail chakra , or some kick ass boost ghost can make up XD , or make Sanbi attack that Island shore instead of mist , the boat traveling could take 3-5 mins and the shops there have things we cant find in the ninja world like new swords , new outfits , etc. .
well thats idea plz tell me what you think about that
