Hey, this is a dialog.
    -> This is choice #1.
        This is a response to choice #1.
    -> This is choice #2.
        This is a response to choice #2. But wait, there's more!
            -> [Variable1==2] Choice #3 is only visible if Variable1 is 2.
                Okay!
            -> Choice #4! [Variable2=1234]
                This sets a variable!
