Simply said, God of War III wraps up the story pretty nicely. The game is beautiful to look at, the gameplay is fast and furious. There is no tapping to open health and mana reserves (YAY!) and the story is really good and helps to put a nice finish to the whole greek mythology arc.
I'd actually recommend the game for those who are action/adventure fans, the game is worth it. Heck, the first stage of the game is worth it to see the Titans scaling and attacking Mount Olympus as the Greek gods fight back, it's a sight to see.
So yeah, that's my quick review on this one. :D
