If it's still on the planning stage, then it has been accepted before so it would. If you made content (graphics, plugins, etc.) specifically for it, you can't use those.
EDIT FROM ADMIN: NOT AN OFFICIAL RESPONSE, SEE BELOW COMMENT FROM Nick_Degica
thanks for the answer, I create graphics for the game (maps and characters with rpgMaker) , if I do the game again, with different graphics, could it be valid to participate with it?
