If you have an idea then tell us about it. Just don't leave us guessing.
If you look at all the other RPG ideas, you will see they are really well developed(For the most part) and have a lot of thought put into them (again, for the most part). You should do the same. put some time and effort into this stuff, otherwise people will never join your RPG's.
Sorry if I seem mean, I just tell it the way it is.
