Okay! I love Role Playing and hoping we get some decent user base soon, I'm gonna suggest few things. These suggestions are from different RP sites that has made them a winner (or so :p).
-> First of all, having stats in the Game is fine. But to actually cover all the 'Role Play' lovers, we need something different here. That is, less numbers and more imagination. Of course, having absolutely no numbers at all will give room for god-modding, that is why I say 'Less Numbers'.
-> Secondly, every Role Playing character must be Approved by a Mod before they can start role playing. This way we can filter out most spams and pranks.
-> And then, I suggest this. Smack me if it sounds too 'Weird'. We should have custom clans, jutsus, bloodlines and what not. These also should be approved by a Mod before being trained and used. This way, it is way more fun.
-> Also, we need to have more villages.
If I were wrong or offending on any point above, please excuse me. And thanks for reading all my ranting patiently. Let's work to make this an enjoyable site.
