Egoraptor's Sequelitis, if you haven't been following along, is a fairly new series that breaks down the game design advancements and downgrades between sequels, while also adding a bit of that manic Egoraptor pizzazz that we all love so much. This latest installment is an addendum to his first episode that compared Castelvania to Castlevania II, this time bringing Super Castlevania IV into the mix -- he apparently hasn't played Castlevania III yet, if you were wondering.
While he doesn't say that IV is a bad game, he feels that by not re-balancing the game to account for the more versatile whip, Konami broke the Castlevania structure. There's no point in acquiring sub-weapons when the basic whip remains superior, and there aren't any new mechanics aside from swinging to test the whip's enhanced capabilities.
I have to agree somewhat with his assessment. Still, it's f*cking Super Castlevania IV, so PFFFFFTTTT to you, Mr. Hanson.
