Machinima

Ever heard of Machinima? Basically, it's the name of videos created using games. Using a visual recorder, game scenes are recorded and editted with real human voices, so that a whole new movie can be made altogether. Some of these popular shows have even yielded a DVD release, and truth is, you don't really have to play the game to even understand the comedy (sometimes).

Find out more at Machinima.com where there are tutorials on building your own scenes and also different shows uploaded by people. Here's one from the popular Red Versus Blue series, from Halo.
