Scripted comedy in games is great - Portal and Monkey Island are up there with any sitcom in terms of writing - but for me two games stand out in terms of delivering laughs on a consistent and persistent basis: - Dead Rising 2 - the ability to combine a plank of wood, a lawnmower,
a chiselled jawline, a serious expression and a pretty floral dress leads to some of the greatest emergent comedy I've ever seen in a game.
