Footage of Kingdoms of Amalur: Reckoning makes it clear that the fateless hero will spend a great deal of time ending the destinies of almost everything he comes across. As Alec's hands-on experience taught him, having an open world doesn't mean an RPG has to be about exploring and collecting vegetables. It can also be mostly about killing things, which isn't necessarily a bad thing. To that end, here's a video showing a variety of things being killed in a variety of ways. It doesn't make me care a jot about the no doubt lore-laden terminology describing elaborate special attacks, but it does make me want to try them out.
I like that subtlety is illustrated with a clip of a man shooting a small creature in the face with a bow at almost point blank range.
