This is the intro cinematic for the second-greatest space combat sim ever made. The first-greatest, of course, is its sequel.

This is the intro cutscene to the excellent 1999 space-based RTS, Homeworld. The in-game engine is dated, but the style chosen for the cutscenes keeps them fresh. The people of a planet discover a hyperspace drive, determine that they had originated on another planet, and plan to return.
