I felt a little let down by the game, not so much because of anything in the game, but because of the design--it's significantly smaller in scale that the previous entries, and a lot more personal. It's the Logan of the GoW series.
The entire game was to deliver the wife's ashes. I had always assumed that would be a stepping point that propelled the game to a larger story, but nope, that was it. When the story ended, I was just sitting there thinking to myself, "that's it?"
And it was a rather cheap decision to not unlock the entire world until after beating the story.
God of War has always been as epic as the name implies... this entry simply wasn't. For what it was it was fantastic, I was just expecting more.
