Demo impressions from a skeptic:
The game feels good. Snappy and responsive. Framerate doesn't seem to be a problem in that regard.
However, I did notice that it made my eyes feel weird a couple of times, and I think that in conjunction with the very fast moving camera it can be disorienting in ways that GOW never was. I guess this is because the camera follows the character much more closely than in GOW, and so when the character moves, the camera usually follows. And Gabriel can move quite fast. Even during combos the camera seems to jump around a bit.
Combat in general is NOT a God of War clone at all. Direct strikes vs. area strikes is different enough from GOW's weak/strong system, the jump button does launchers, rolling doesn't seem to make you invincible. Despite being based on a ranged melee weapon, it feels quite different.
I still don't like blocking with L2. When I was trying to practice the block-counter it seemed to take a bit too long to bring up the block, meaning I have to press it a bit earlier which is something I'll have to get used to. Maybe this isn't because of L2, it could just be the timing of the block move.
I had defended the writing in the game earlier, and I still think it's perfectly acceptable for a game, but as I read the text on the load screens I started to notice more and more things that I would've written differently. I think people are on to something when they say that Patrick Stewart's voice makes everything seem better than it really is.
Oh yeah, and the graphics are good.
So I definitely want to play this, and I was fully ready to buy it for $40 from Amazon (factoring in the credit) but I'm probably going to Gamefly it now and if I really like it, buy when it's cheaper.
