GameTrailers have recently uploaded a run-through preview for Final Fantasy VII: Crisis Core. The video explains the Mission system, Materia, Gameplay, and how the DMW Battle System works.
We also get glimpses of the soundtrack (including music very similar to the original Final Fantasy VII), as well as a sneak-peak at the game's stoaryline and characters (who, as we all know, also appear in the original FFVII).
