Not as strong as the original 2 games of the series but still worth a play through...
While the boss fights can be difficult they are never too impossible to complete but can be frustrating. Even on Normal mode I could barely get through the game and could not imagine playing the harder modes. This game is not nearly as interesting or epic as the great original game of God of War for the Ps-2.
Instead we get a chopped up story with a game centered around big boss fights and little else. The game lacks the mystique and intrigue that made the first one a classic.
After just one play through I had enough of this game and had no interest in a second run.
I recommend the game if you like tough boss battles and nonstop action but you will most likely be bored out of your mind after 5 days.
