Good old Nintendo localisation - The Legend of Zelda: Twilight Princess contains a cheeky reference to the common practice of charging people in one region one price and a different one elsewhere for the same goods. I’m not sure I totally let Nintendo off the hook just because they’re wry about it, though… (price of a US Wii = $250/£126; price of a UK Wii = £180/$353, cough)

On the topic of other nice little socio-economic comments in Nintendo games, there’s also the KK Slider comment in Animal Crossing Wild World. “Those industry fat cats try to put a price on my music, but it wants to be free,” says the musician dog, before handing your character a copy of the song he just played for you.

Can you think of any more?
