Although there are many people who dislike this series because of their infamous fillers, anyone who steps back and looks at it for a second could tell that the story and world of the Naruto Universe could transfer into an MMO, without even having to touch the storyline, or alter anything about the world.
If you have seen any parts of the series, or even heard about , you should already know that within this world there are many major factions, and many different "Classes" of shinobi. Almost a perfect set up for a Faction based game. All players could start out as a trainee ninja, and depending on what "specialization" tree they follow, they can be anything from a medical ninja, to a genjutsu ninja, or even a hybrid between all!
The possiblities with this series are endless.... And since they are making so many pirate MMO's i feel its time to give the ninjas a chance.
Whereas Naruto would transfer smoothly, with bleach there would be a few things which could be minor setbacks in transfering this world into an MMO.
There are two main ways you can really do this,
1. Use a current-day bleach setting and do a faction war between hollow/shinigami. Only setback is how you are going to get the hollow faction to work in game. (With progression and whatnot)
2. Use a Pre-Anime setting, and have the story take place way back when the quincy were still a part of the world. Which could make this a PVE focused game, with a little bit of bitter rivalry between the quincy and Shinigami.
In this game the MOST complicated thing would be figuring out how to get the leveling system to work, because shinigami do not interchange weapons, or really gain many "skills" in their progression. So the only thing which i could say sounds feasable in this situation is to be assigned powers based on what squad you join. And you specialize through "unlocking dormant powers inside you"
I.E. Lets say you became a part of the medical squad.......Once you have reached a certain "rank" , a prompt comes up saying that you have learned a new ability. And when it comes up lets say it gives you a choice of 2-3 different ones you could pick from.
These abilities scale in power when you level, and there is never a need to "upgrade" them. Which makes it so each person has their own sense of individuality in the game.
Self explanitory. The game is already there they just need to make it.
I know they tried it out in Japan and it didn't work, but what could your really expect from an MMO which wasn't truly an MMO. It was more of a party system in the .hack world.
I know there have been many attempts at a Robot Sci-fi based MMO, but i believe that a Zoids MMO could outdo most of those out there. Story-wise, and gameplay wise. Think about it, you start out as a person, you go through a tutorial, and then after you get to choose your type of zoid. And while you travel, saving cities, and destroying other wandering zoids, you can pick up a variety of parts to upgrade. Making for almost a limitless amount of customization available for your zoid.
Can't you picture it? Epic 100 vs 100 battles of Liger Zeros, and Thundertritops, fighting for control of the world?
Well these are just my opinions..........Feel free to ADD whatever you think would make a good addition to this list, and let me know if you like my ideas :)
