I want an RPG making tool

I want an RPG making tool that can be edited on their own Android stage, setting, character, story and so on.However, although technically can be done, but it is undeniableNot all games are suitable for all platforms.For example, all the controls on the phone, not suitable for playing a pure RPGEven if it is not fun to do, then it is not necessary to make ~
There are many more ideas that can be, but I think the new platform will have new ideas.
