The art of game design is a subtle, delicate craft that requires expertise, dedication and ingenuity to truly master. It's a skill that also goes largely uncelebrated, considering that the best game design is often unnoticeable when properly implemented.
Sequelitis, a new YouTube series from Awesome Series creator/animator Egoraptor, takes a hilarious look at the philosophy behind game design by comparing an original title to one of its sequels. The latest episode (above) takes a look at the differences between Castlevania and Super Castlevania IV, and how changing the whip and jumping mechanics fundamentally altered the game's structural underpinnings. It's a fascinating and remarkably entertaining way to learn about game design, so be sure and check out the first two episodes when you're done here.
