The Diablo Formula and how Diablo 3 falls short

[Jester]

That's what made Diablo so innovative. It leveraged random elements and clever algorithms to allow the game to create new content on its own. New content is fun to play; it maintains the player's interest and keeps the game fresh.

There's a reason they called it a roguelike. Procedural generation was not new - it was just innovative to combine it with an A-list, high-graphics, real-time game.
