Inter-game reference is the best thing. It’s the hip hop soul on show in Super Meat Boy and a thousand arcade fighting games that sees the familiar flipped on its head, the solemn made hilarious and the trite made meaningful by new context.

Referencing makes two games stronger. And sometimes, it allows you to watch TF2’s Heavy and Total War: Shogun 2’s iconic samurai duke it out on a cartoon race track.
