Let's Players
Let's Players or by their more racist unfounded term "Retsupurae" are live streaming entertainers who set up their computing units, various video game related hardware up, and new age internet video broadcasting hardware to properly showcase themselves playing various video games to a wide live audience online.
They have gained a large degree of popularity and even notoriety regarding their fame and renown, especially since the rise of internet based entertainment. The dynamics of the entertaining factor of Let's Players are usually from a mix of hosting personality and ability from the player themselves, the kinds of games the player has in their library and lexicon, their skills in video games, charisma, and to how sessions are reminiscent of times among the audience when players played video games together with friends and/or family in their youth.
Likewise with Let's Players, there are plenty who are entertaining but many who are outright scammers and assholes.
