An intro sequence is a non-interactive introductory sequence for a computer or video game. Previously, intro sequences were very often prerendered, hand drawn, or otherwise outside the main game engine. In recent years, sophisticated game engines have been able to render graphics of comparable quality to ray-traced sequences, allowing modern intro sequences to take place within the game engine (Unreal Tournament), or even as a scripted subsection of the game (Half Life).
The term "intro sequence" is used almost exclusively in the game industry. The non-abbreviated term introductory sequence usually refers to the opening of a film. The game term obtains meaning from the film term, as games use intro sequences to create a cinematic atmosphere.
Before the advent of powerful 3D video cards, the mismatch between what a game developer's workstation could render without time constraints, and what the target home computer could render in real time, was large enough that games would nearly always include some kind of scene or mood setting intro sequence.
The interactive movie genre, and games like Myst, whose graphics are almost completely pre-rendered, are a separate phenomenon.

Famous quotes containing the word sequence:
“Reminiscences, even extensive ones, do not always amount to an autobiography.... For autobiography has to do with time, with sequence and what makes up the continuous flow of life. Here, I am talking of a space, of moments and discontinuities. For even if months and years appear here, it is in the form they have in the moment of recollection. This strange form—it may be called fleeting or eternal—is in neither case the stuff that life is made of.”
—Walter Benjamin (1892–1940)
