I finished it a couple of hours ago. It was way better than the first one if you ask me. Personally I didn't like the 1st one to much, it somehow lacked for me. However, after being introduced to the theme and gameplay by the 1st one, the 2nd was really great. This time I knew that Kratos is a bloodthirsty beast which does the impossible and got to enjoy it better. The story was upgraded also.The 1st one left me with many questions like "what did Kratos do in these 10 years of serving the gods?" it was incomplete for me.
Anyway, it was great, it was nice seeing new weapons and abilities and how he's planning to kill a God again. The gameplay is more awesome than last time, you get to play in the first time. You get to play in the 1st missions as the God of war, great. And flying was awesome
