Gamasutra has an article analyzing random events in games, and how they can add or subtract to a player's experience. It looks at the different ways luck plays a part in games
; from landing a critical strike instead of a miss to the scatter of a shotgun blast to waiting for that blasted straight piece in Tetris
. "Game developers are sometimes faced with similarly challenging decisions when contemplating whether to include some kind of deliberate randomness. For example, in the video game Unreal Tournament
, when a player shoots at a target with the 'enforcer' weapon, the projectile does not necessarily hit the point that is aimed at; a random deviation is added that scatters shots. This introduces a degree of realism from an observer's perspective and no doubt gives beginners a fair chance against more experienced players, but it can also potentially frustrate skilled players."
