You need to know who your friends are before playing Fable 2. One of the best new details revealed at the Game Developer Conference, online co-op, quickly became one of the more terrifying during the demo: Peter Molyneux invited a friend to join his game, only to see him kill his spouse.
Admittedly, it wasn't a very warm family scene to begin with. The Molynator (actual GamerTag) was playing a female adventuress who hadn't been home for six months, so he wasn't receiving a warm welcome. His six-year-old son laid on the guilt, "Don't ever leave us alone again!" and the husband was gearing up for a more extended whinge when the henchman became bored and slayed him. And started pointing and giggling.
