I recently took a look at the phenomenon of Machinima for Complex:
There is no fan-made creation as unique to videogames as machinima. Part fan film, part software hack, machinima (a word created by mashing together “machine” with “cinema” into an Internet Age portmanteau) is an animated movie made by manipulating the 3D graphics of video games to cinematic effect. Born of recording speed runs and multiplayer matches, the phenomenon came into its own with the release of Quake. Machinimists – both fans and professionals – have since created scores of movies, from comedic shorts and television shows to full-length films.
Take a look at my picks for the 15 best machinima videos of all time, only on Complex.
