Responding to my own comments above:
I've had a change of heart on the matter. I saw another few hours of God of War, and quite frankly, the combat (i.e. gameplay) gets a bit stale after awhile. Maybe because I was playing on hard, but enemies took a ton of hits, and I don't mind hard games, but some of the combat just got boring after awhile. And the minotours suck, because I am unable to perform that rapid button mashing thing with the circle button for a finishing move (am I alone in this?)
As far as aethsetics go, God of War wins hands down. I loved the variety of environments, textures, enemies, etc. But after awhile I found myself propelled only to go on to see what new places lay ahead. Now some people may say that that's a sign of a great game, but nifty graphics and art design do not make a great game. God of War made me realize how easily duped we are these days into buying into games that look like cool movies, regardless of gameplay.
God of War's combat isn't horrible or anything, but it just gets stale, which is bad since it's about 95% of the game. I still say God of War is a good game, but not a great one. After seeing about two-thirds of the game I have no desire to replay it again for quite some time. worth a rental, but not as good as it looks.
RE4 wasn't exactly the second coming of Christ either, but it had more variety in its combat scenerios. The variety of enemies was less, but the area design in which you face these enemies totally changes how you deal with them, where as God of War was the same old thing against a bunch of pretty backdrops. So all in all I change my vote to RE 4.
But don't feel bad about the PS2; Okami looks to be the best game at E3. Yes, even better than Zelda.
