I enjoyed it immensely and recommend it for those who are willing to endure the unblinkingly violent images and occasional partial nudity.
That said, I still have some complaints. There is a section late in the game which overwhelmed me with a bunch of cheap tricks: conveyor belts, flame jets, archers, and harpies by the dozen. Even after I figured out the best way to optimize my limited resources in that battle, I had to endure several attempts before I got lucky and survived to the end. Even the last three battles, the climax of the game, were easy by comparison.
For a man broken up missing his wife and child, Kratos sure didn't mind hopping in the sack with a couple of pneumatic floozies at the beginning of the game. That bit strikes me as an exploitative stunt which mars an otherwise well-written story. It's particularly noticeable because of the two teenage fantasies the game glorifies, violence and sex, only the bloodshed persists beyond the first third of the game.
You know, there's been quite a bit of the sort of "cheap" shots in games that otherwise mar an otherwise stellar game.
For instance Dark Kingdom (for the PS3) is a fun hack'n'slash, until you get to "The Grinder". I won't spoil it for anyone, but needless to say, it's unnecessarily difficult and detracts from the otherwise fun Diablo-esque gameplay. I am currently at the Grinder stage, and haven't played regularly since a death-fest of about 3 hours convinced me I should let the game rest for a while. There are some people who doubtless have gone through the Grinder with minimal scarring, but I'm not that good. :-)
I know most people don't care for Dark Kingdom, but it's a recent example of the next-gen consoles going for artificially difficult sections to stretch the game out longer, or to ratchet up difficulty with no rhyme or reason.
God of War is on my list of "to do" games... and I'm glad it is as good as the hype has been... albeit not 100% perfect. :)
Psychonauts had a similar section near the end where the difficulty just spikes for no apparent reason.
Or, if you want to head even further back into the time tunnel, there was Syndicate's "Atlantic Accelerator" mission that I saw Peter Molyneux apologizing for years later.
