Funny thing is, there are three dragons in the Game of Thrones. But back in the 1970s the original dragons from Atari were there first. Coincidentally they even have the same colours of red, yellow, and green. Is this just a coincidence or should Atari claim some credit for this show?
The red dragon of Atari was Rhindle, which is the Viserion the red dragon in Game of Thrones. Both red dragons are the most aggressive and fearsome. The yellow dragon of Atari is Yorgle, who was reborn as Rhaegal, and the green Atari dragon is Grundle, aka Drogon. Coincidence? Or maybe the creators of Game of Thrones loved the Atari's Adventure? Who knows?
It all makes sense now, since you basically play as John Snow in the original Atari game. In 1970s glory the game Adventure could have been called Game of Thrones 1979? Maybe they'll repackage it?
Subsequently the castles all fit into place the White Castle is actually Winterfell. The Black Castle is the Castle Black—THE WALL. It all fits into place. Adventure was indeed, partly, the source material for Game of Thrones. Those weren't bats! They were crows!
