All though its a basic unity game i see it having a big future. These are some of my ideas although it will take a while for what we all want to get here.

Character Customization:
Appearance Wise there should be hair, skin, height eyes (Not kekkei Genkai)
and human stuff. But clothes i think it should not be limited to you village or homeland.
If you are a messenger or wanderer you should be able to wear any clothing at all. I would wear the robes sasuke wears in his training with orochimaru

Jutsu:
The way i see it every chakra nature EX : explosion release, ying yan release should all have a different set of hand signs and justu. and of course you should be able to get new jutsu if you Are fire style but want water style, but you would have to earn or learn it

What you guys think?

To add to that. That would be  really easy. Some missions maybe b - class might require you to kill rouge ninja depending on their ability in-game. And also your status shouldn't go away unless you bribe someone high in power or start life in a new village
