Where did the Dark Souls/Demon Souls hard boss fight type of style develop from? The earliest I can remember is Batman Arkham Asylum that used a sort of 3rd person with a rotating camera when battles occured. But I'm sure there were other precursors that I don't know about.
I've seen many games use the same boss fight telegraph/memorize moves games, like Monster Hunter. Is that where it originated? I have no idea, someone more knowledgeable can take the reins.
