Red Faction kick-started the whole destruction trend almost single-handedly way back in 2001. Since then there was very little progress in terms of destruction until 2006 when LucasArts promised to revolutionise gaming with its Digital Molecular Matter (DMM) engine in Star Wars: The Force Unleashed. DMM showed off spectacular destruction based on wood shattering exactly like real wood and metal bending just as it should, but in the end we got a game where the DMM tech was only applied to a couple of crappy doors. LucasArts put all its destruction hype in the 'too hard' basket and consequently left the door wide open for Red Faction to impress us with its large-scale destruction.
