From various sorts of novelty controllers that nobody wants or asked for, to more esoteric and unnecessary add-ons, gaming history is littered with failed devices which attempted to make a few quid out of somebody else's good idea.
Here are but ten of the stupidest.
Again: essentially a chastity belt to keep the NES pure and unsullied.
Note: In the UK, we know "skeet shooting" as clay pigeon shooting, because in this country we call things by their proper names.
I've done clay pigeon shooting a couple of times, and concluded that it's one of those activities - along with being able to play pool, and liking football - which is regarded by some as crucial to their masculine identity. Apparently, it's really funny when a man can't shoot a little clay disc out of the air... and that's fine, so long as I can laugh at how emotionally stunted you are.
Let's face it, at least you won't be able to acknowledge how hurt you feel when I do.
Also useful for tenderising very small steaks, or as a very ineffectual automatic hole puncher.
Check out the sinister doctor in the image above. Why are they both laying on a crushed velvet bed?
"It's better for soaking up the blood while you eat their legs."
"That's a bit of a dark joke."
"I just call it as I see it."
Even more excitingly, the Singer Izek could "do buttons".
Except when you hide their insulin, and they start sweating and trembling and vomiting. LOL! Get that on camera - we're going viral!
"Neither: it is a fresh trout, and that is how it talks."
The pocket Bonar - sorry, Sonar - attached to the Game Boy at one end, while the other was dangled into the sea or river. Passing fish would show up on the Game Boy screen - and if that wasn't boring enough, there was even a tedious fishing game included.
Dong... dong... dong... (sonar noise).
"There's a big dong coming from your pocket."
"Yes, sorry about that - there's a hole in the lining."
Makers CTA Digital boasted that the Wii Wings "add a sensation that you will not feel mimicking a flying chicken with your hands alone."
The name of that sensation? Shame.
Also: "less hand fatigue" apparently. Does anybody really suffer from that? How many days do you have to be playing a game before your hand begins to tire of the very slight movements your fingers make on a joypad?
If that doesn't sound pointless and over-the-top enough, the device's creators at N-Control topped the Avenger with their Delta Six first-person shoot 'em up controller - the "the most realistic, immersive gun controller on the market."
Alternatively, you could use it as a chopping board.
