The God of War III game demo was first revealed at the E3 2009 gaming expo in Los Angeles. The game will be released this March. And my, how the game has changed.
For the better, too. The DigitalFoundry blog has side-by-side comparisons of the demo and the final retail game. Things to notice? The retail game has much richer lighting and more realistic ambient lighting.
Other additions, DigitalFoundry points out, include film-like "motion blur" and "effect optimism". More detail and refinement has been added to the finished product as well.
