Can anyone think of a game where the twist is YOU are the final boss?
Only one that comes to mind for me is Shadow of the Colossus.
(Though the bad ending to Resident Evil 9 totally missed an opportunity there)
One time I entered a tournament with this & knocked 3 of the top 32 players out by pumping it's defense. The look on their face as they attacked a 12,000 DEF wall will never be topped. I think that's the Spirit of Yu-Gi-Oh! Using BS strategies that somehow work, but shouldn't.
