What do you get when you combine the opening of Game of Thrones with the SNES classic, Super Mario World? Poetry. Pure, 16-bit poetry.
You might not see an immediate corellation between the Mario Brothers and George R.R. Martin's fantasy epic, A Song of Ice and Fire. And so you shouldn't. In Super Mario World, there's no Iron Throne, there are clearly defined good guys and bad guys, and also there are friendly dinosaurs instead of terrifying dragons. The two things they have in common is lots of death (seriously, Mario steps on countless heads) and a bevy of different kingdoms.
But that's all you need.
Point of order -- I'm pretty sure that's Link's Master Sword from Legend of Zelda: A Link to the Past at the beginning.
