Euphoria is the name of the new game engine which i believe is just opening up the gaming world to what it should be like. the physics in this thing is superb they actually have molecular matter movements down to a T.. take a look at the demo of the engine and please watch the ingame play shots for star wars force unleashed.. there is no more rag doll movements so to speak people will move based on whats happening and so on.

The unreal engine is dead as far as i'm concerned. One Game engine to rule them all (http://www.gametrailers.com/player.php?id=17054&type=mov&pl=game)

Yes i seen it in action, it still needs work...but its on the right track
