Okay, I have just watched the gameplay 'reveal' trailer again and this is what's wrong with it:
When I first watched it - I was thinking GoW? With a kid? Looks like Kratos, but it doesn't sound like Kratos (different voice), and he certainly isn't acting like Kratos. What I did get though was very much a "Witcher 3" vibe. So much in fact, that at first I was wondering if this was some crazy extension pack to Witcher 3 they were showing or something. It wasn't helped by the various messages popping up "Archer skill improved +1" or something along those lines. Now I absolutely loved Witcher 3 - for what it is. A grand-scale, novel-like, story-driven RPG. I certainly wouldn't play Witcher 3 for the combat. It's just a means to level up and progress.
This is not GoW or what a GoW game should be. To those wondering what a God of War game should be like, you should look for the GoW3 topic and see the people (me included) raving on about how bloddy fantastic the gameplay and combat were in that game. It was what made you come back and play the game. Heck, I completed it on the hardest difficulty setting and was about 2 challenges away of getting a Platinum trophy for it. It was one of these rare games that made me feel like a little boy, playing something mindblowingly epic.
It's a pitty they seemed to have changed the diretion. This neither feels like a God of War game nor have they shown anything so far that plays the part too. IMO this just looks like Geralt dressed up as Kratos in another day of the Witcher 3.
Mighty fail if you ask me, sorry.
