Randomness

My mother is a fish

Diablo 3 will add even more randomness than the previous games in the series. "We don't place a lot of things by hand in groups that are pre-planned," Martens said. Monsters will rarely work as a team—that's not in their AI design.

"We don't need that," Martens continued. "We look at a zone holistically and make sure all the monsters that appear in it can work together in interesting ways, and then we tweak the random possibilities to maximize those interesting ways—without making it repetitive by actually placing them down in the same sequence every time."
