Seinfeld Horror Game (Trailer) But was this a real game? Turns out YES, it is! Seinfeld: The Horror Game was created by RareBird Games. The premise is that you are Jerry’s nephew, Donathan and you get to explore Jerry and Kramer’s apartments, Monk’s Diner, and other places made – all of which seem to appear to be….empty. The gameplay sees you playing as a character named Donathan “as he survives the streets after his newly adoptive father abandons him at about 3am in the Big Apple [and] finds himself trapped in an endless loop of nightmares as he fights to find a bed to sleep in.”
