The game is good and well put together, but I cannot say that it's the best of all time.... that distinction, for me, still goes to The Legend of Zelda: Ocarina of Time. I personally felt like the story line wasn't starting to captivate me until the game was over, then it was OVER, unlike Ocarina of Time where the storyboard layout was perfect. In fairness, I think Ocarina of Time is a longer game with less side quests while this GOW reboot has a shytload of side quest and just a little lacking on the story. I'll give this game the benefit of the doubt because it is a setup game... the next game should be EPIC!
I've almost completed every region at 100% minus the trials at Muspelheim and Niflheim... getting the mist is a bytch. I have that last Valkyrie there too.
