I completed this magnificent game yesterday after spending around 40-45 hours playing it, ensuring I fully explored as much as possible and did all of the side-quests except for one (or rather seven!) really difficult ones! The ending is really touching but those credits you see rolling down the screen as you head back to mop up the rest of the side-quests and content, no, the real ending happens when you head home so make sure you do that. It's a sign of just how great this game is that I still want more. There are three areas in the game that, as far as I know, are not accessible yet so I can only hope that Santa Monica Studios have an expansion or two planned for the game and that we won't have to wait three years for the proper sequel. God of War is definitely the best game I've played by far this year and I can imagine it will only be topped by Red Dead Redemption (if that is released in October as Rockstar don't have a great track record when it comes to meeting release dates).
