Yeah, can't really argue this. "I am Ozymandius, King of Kings," and so forth. People know the rulers of Ancient Egypt, Babylonia, Assyria, and so forth mostly from various monuments they erected (and some clay tablets that got a little overcooked). Nobody really remembers how stressed out they were or how hard they worked (with a few notable exceptions who were complained about in stone or writing by subordinates)
Luigi becomes a Ringwraith? Innnnnnnteresting... Might be how we get Waluigi? Alt, you could have Mario working with the Fellowship, Luigi trying to coerce him to join Sauron
Luigi should know better, you don't turn your back on a wraith, they can only chase you when you your back is turned.
