You guys read what you wanted, not what i suggested. The person would need to have the jinchuriki bio in the normal RP. But instead off rping as lets say Roshi, the user would RP as himself but wielding the abilities Roshi has. Not the same as allowing custom jinchurikis or rinnegan.
Also, i keep the idea that only one bio (for use in this IC suggestion that is) would be best. If we are to RP in full, we can't have it any other way. However, the issue of lives is easily dodged or avoided with the idea that exists in all sorts of games and was introduced in the first Unreal Tournament Game: Respawn. Basically, when you die in a battle, you respawn after some time at a certain destination. In this case, since we would introduce the village system in this, you'd respawn in the village after a set amount of time.
However, i have some minor issues that bug me a bit. As you all know, the amount of people that would actually be able to RP decently or within the concept that Zero suggests is very low. It requires 2 things that many members have trouble with: proper english and imagination. This would lead to tons of spams and "wrongful" behavior. So, for that section to work, an almost Zero Tolerance policy to spam and non RP behavior would need to be introduced. This would make the section available only for a low percentage of the RP population which in essence would lead to tons of complaints and anger towards it. How would one avoid such issues?
