just played it through and wanted to share my opinion:

THe main game is, as everybody already knows, quite short and finally disappointing, there is no real feel to it, the DLC was probably supposed for the main game and cut out in order to warrant extra income. The effect is that both feel a little disjointed. The main game being short, the DLC being tedious, it almost felt like a chore, played the whole betrayal thing ;(, started the vendetta and couldnt stand it after a couple of missions. Then I played Joes adventures, didnt wanna play it until the end though... am gonna re-sell it, what a waste of time and money, luckily I waited on the platinum version together with the DLC... it could have really been a great game...

IMHO Ninja Gaiden is the better game!

I played 'black' on the xbox (never owned a PS2), and really, really liked and appreciated it, the story was quite forgetable, the characters, well I liked RYU but the rest of them were also forgetable, music? I didnt care...

Now that I own a PS3 I thought I would give the GoW collection a chance and if its good I would buy GoW3

My experience: I was quite disappointed from the beginning!

First: The camera is not movable, which means you will always have a preset camera, I didnt like that too much

the gameplay, I dunno, Ninja Gaiden (havent played the sequel yet) was quite fun, I mean every fight was an experience, whereas I felt like each fight in God of War as just another annoyance. You dont really feel like you're attached to the fighting in NInja Gaiden it felt like being one with RYU, GoW is a littlebit more distant

the story is actually forgetable as well in GoW IMO

the blades or the weapongs in GoW, totally forgetable!

cant wait to lay my hands on both sigma titles.... and resell the GoW collection, GoW has become a no no option
