I know we have like Hoshigakure and Ninja Central but does any besides me actually wanna have different races to choose from like Cloud Rock Rain and Grass and other vilages like Kumo and Tamigakure. Just saying
To be blunt:
Yes, it would be cool but just a matter of things:
1:
Don't need it-
Quite frankly being a different race is not of our concern at this moment, nonetheless you will have to introduce new types of attributes each village contains.
Example:
Sound:
Gains extra attack and speed
Sand:
Extra forest fight each day and extra defense
And so forth.
We don't need it, though we may WANT it, it is just a waste at this point.
2:
Populism-
Quite theoretically shinobilegends is inhabited by over 500 (Hit or miss) players, keep all of them content seems highly impossible. All the same, one must take into consideration how much people like the current system.
Example:
If one is tied between to options, it'd be rather difficult to come to a conclusion on what they desire more.
Tie that to --> village choices
On a simple note people will not like that broad range of things available because it will make harder choices.
3:
Complexity:
Each village is assigned a special attribute to them (or most of them) and with new villages will come new modules/shops/etc.
And blah, blah, blah yadda yadda in simple terms:
It may seem easy, but really there's too much work that needs to be put into it, and Neji just doesn't have the time.
Mind you this is all constructive rather than an attempt to dismantle your dreams. New villages might be put in someday; who knows.
