Just good old Nin Online:
Features:
1. More interesting mob mechanics, have mobs display danger tiles for jutsus & more randomized movement to keep pve more engaging than simply running circles until flicker is on cd or getting flickered on for several 100s of damage auto attack.
2. Unique election systems for villages.
Think of an automated 1v1 tournament for mist, and in sand a kage would set 3 players as his siblings at the start of a term, at the end of his term the kage would get a popup needing to select 1 of them to be the next kazekage. Stuff like that to make the villages regain their uniqueness vs alting/voteabusing
3. More incentive for dangerzones, could be stuff such as having a certain time a day where in a random dz map bosses spawn for an hour with increased droprate. Which map it is would be announced slightly beforehand or as soon as it starts. So people can choose to go there and farm some better droprates with the risk of being attacked by others.
4. Mission board (saw a suggestion that I thought was cool) instead of grabbing random dailies, have a board with randomized dailies of which you can pick i.e. 3 dailies, you pick one of them and after handing it in 3 new randomized dailies are on the board. That way people have some choice in terms of their playstyle for leveling
5. I already know it's on the way, but the completion of the gathering/crafting, this way there's a reason to get the materials vs people just botting it for ryo for it to get nerfed to the ground and undesirable to make use of
Optional:
Make regular NPCs just like jonin bots killable, so the next time some hidden leaf spy npc destroys my traps in sand he gets cloak bombed into oblivion
