agreed, you must make the game balanced, but very challenging and you have the choice to become the ultimate ninja.
im surprised no one has already thought of this :|
Precisely. We can't have OP ninja's with rinnegan/MS/byakugan.
What would make sense is someone who has the EMS has the potential to evolve into the rinnegan. But that would take months to fill up the experience bar. SO to have it would be an incredible feat that not many would have or have the patience to work for. The sharingan (includes MS & EMS) is less rare but the requirements to upgrade are still challenging but not like the Rinnegan.
For KGs you can take 2 routes.
1. You can collect items hidden in the maps. Much like farming. COllect them and you can unlock a KG.
2. the better choice would be to have specific KGs clan exclusive. Meaning FTG could only be for Namikaze clan or Wood Release for Senju Clan. But in order to unlock it you have to meet the element level requirements to unlock the KG.
You see? Now I have gotten caught up in this. This game better not be those lame ones like on Beyond.com where you make these geyass mmo's.
Anyways, good luck to sky and his team.
