In the 80s, video games were still new to the public and the game companies were still trying to figure out how to ease us into the technology. From their early ads, it appears they decided the best way was via batshit insanity.
6Nintendo Australia/New Zealand Ad
When Nintendo brought the NES to the US they rolled out about the most run of the mill ad ever: just a kid, the games and an announcer announcing how awesome it all was.
But when it came time to bring the NES to Austrailia and New Zealand, they unleashed an ad that crawls inside your head and kicks your brain in the balls.
After a great deal of market research, apparently all Nintendo came up with was "Well, those Australians seem to drink a lot and are boastful by nature, so let's threaten their well-being and take shots at their self-esteem." Their plot to make you feel horribly inadequate is carried out by some of Nintendo's classic villains, like Poor-Man's Max Headroom in a Dress Shirt and of course, That Dog from Duck Hunt.
Welcome to the end.
Wait, what? The fucking dog from Duck Hunt? Was he really even a villain? He's got a creepy voice, sure, but he's a mild nuisance at worst and a jackass at best.
"Ha ha! You'll never satisfy a woman!"
Our blocky league of evil goes on to tell us that they are Knee-Ten-Do, which we can only assume is an elite terrorist organization of some sort. The only kids they show playing games are doing so in an empty dark room, as though they've been abducted and forced to play games, constantly being reminded that their opponents are invincible (even if they have zapper and robot companion). However, given that the zapper doesn't actually cast bolts of lightning and the only thing the robot does well is spin tops, we'll go ahead and agree that we cannot beat you.
As the commercial draws to a close, we do manage to encounter an actual villain in Bowser, King of the Koopas, who makes the ad's worst transition from blocky thing on screen to three dimensional blocky thing on screen.
The whole thing ends with the Legion of Doom challenging all players and, again, letting you know they are unbeatable, and that they'll be turning up in your nightmares later. Yeah, we'll head right to the store and give you fuckers $250.
