There had been lots of fan art and videos of imaginary 8-Bit Stranger Things video games. As the show was set in the 80s it was easy to see why. However, Netflix have finally released an official game and you can play it here.
Sadly it is very basic, you just jump over things, but it does waste a bit of time. There are also games based on Orange is the New Black, Marco Polo and Narcos.
