Those who are looking for an immersive title will be very satisfied. God of War more than delivers in terms of production values, breathtaking visuals and mind bending audio. Camera work is especially impressive, with a near perfect framerate going on even in the most hardware-demanding scenes.
Unfortunately, not so much can be said about the actual gameplay itself. A lot of hand-holding takes place as the game unfolds, and most puzzles solutions are hinted in a too-obvious manner. The real challenge of God of War is definitely in the button mashing the game will expect of you when pitting your avatar against immense bosses.
Personnally, I've played the game for around 5 hours straight, and while I enjoyed my time with GOW, once I put the controller down, I never went back to it. The storyline is average at best and the gameplay generally lacks the exploratory stimuli (both spatial and structural) or interesting rewards that usually makes me crave for a game.
God of War is definitely a like it or hate it title, that deserves your attention if you are a fan of highly polished action titles. It won't show you anything you don't already know, but to it's defense, sequels were never made to do so, and it's perfectly fine that way.
