There are numerous great video game accessories—flight sticks, steering wheels, VR headsets, and many more. However, for every awesome accessory there are ten that come across as just a little silly. While I could probably fill a book with them, these are some of the most (in)famous examples.
Even if you have no idea what it's all about, you've most likely seen the Power Glove. It's become an iconic part of video game history and pops up in all sorts of media. People love the Power Glove, but it was originally intended as a real gaming controller where you could use the movement of your hands to control your NES games. It was manufactured by Mattel in the USA, evoking the idea of virtual reality which is something completely outside the realm of possibility for household computing in 1989.
The truth is that (by all accounts, it wouldn't fit me) the glove just didn't work very well. You'd be better off just using the NES pad instead. It was (and is) undeniably cool, but also 1000% silly.
I'm not going to rehash the whole saga of the US video game crash in the 80s and how Nintendo had to carefully finesse its marketing and product design to convince skeptical buyers to forget how Atari burned them with games like ET.
Part of that marketing magic was R.O.B—your plastic pal who's fun to be with. Sorry, wrong franchise.
R.O.B is a toy robot that can be integrated into a limited number of games. This helped sell the NES as a toy rather than a video game system, but as a gaming accessory it's pretty high up on the silly-O-meter. As a Trojan horse to get NES consoles into US households, it's less silly, and probably did help Nintendo get a foothold, but I suspect most kids probably got bored of R.O.B quickly despite my boss here at HTG insisting everyone thought it was cool. I wouldn't know, since R.O.B. is one year older than I am. I guess you had to be there!
