It's all about the style!
The story is very interesting, this surprised me since I was expecting something weak just to tie together the different combat sections. Talking of combat... well it's almost perfect. Your weapons and magic are so mush fun to use and again all the combos and attacks you pull of are very stylish, and when you get to perform the quick time events, what Kratos does just feels so satisfying such as when he rips enemies in half or slams the blades right in their face. The boss fights are amazing. There's really only 3 but one of them has multiple parts throughout the whole level, the second is just really long and crazy, while the third is massive and you really want to kill this dude by the time you get to him. The game also contains a lot of puzzles. They're difficult but not impossible, plus you could always use a guide to help out.
The audio in the game is also great. You hear epic music everywhere you go, and the crunches, and screams the enemies make are sweet! I really enjoyed playing this so I'd really recommend you buy this.
