Rockstar Advanced Gaming Engine: that is what RAGE stands for. All you need to know though is that as middleware solutions go, Rockstar San Diego's RAGE game engine is up there with the very best of them. You would have first seen it in Rockstar Present's Table Tennis making cloth flap and balls spin. Then in GTA IV and Midnight Club: Los Angeles. Next up it'll star in Red Dead Redemption, the game that Rockstar has gone on record saying inspired them to build the engine in the first place.
