So clearly there's quite the amount of similarities between the level shown in that video and the underground cavern, The Forgotten Depths in ToT. Is Blizzard just paying homage to this great game or what?
For those who don't want to watch the video, it's a video of the level "Cave of Hydra" from a SNES game called "King of Dragons". The stage is literally a 2d version of the Forgotten Depths who's boss is a 3 headed Hydra. Not only is it a three headed Hydra, but the Hydra's heads consist of a blue necked with ice attacks, a red neck with fire attacks and yes, a green neck with poison attacks. But that's not all! You only fight two of the heads at once. The third one stays in the back, off screen and invulnerable, until you kill one of the other heads.
So is this just one of the many throw backs Blizzard has in their games? Is this blatant plagiarism? That's for you to decide. I have my thoughts, what are yours?
