Isnt this game a bit redundant, story-wise?

I mean, it looks like a fun game, I'm not saying it will be bad or anything. But with the two PSP games, isnt that the third prequel we have to the original God of War trilogy?

I know that it doesnt seem there could be much to be done with a sequel to the third game, seeing how the world is done for and on the verge of destruction, but couldnt' they go in a different direction? A prequel, story-wise, has always had to me a very limited appeal since we already know how it will end. The only thing we do not know precisely is exactly how the pieces of the puzzle will fall in to become the outlines of the next installements, but it limits the way the story could expand. And seeing as this is another prequel, I do have to ponder how much more new backstory they can add to an already finished saga.

I'd really like to see what happens after GoW 3. Say the world is rebuilt by newcomers, norse gods for instance, and that we get a new protagonist to carry on Kratos' fits of endless destruction. Wouldnt that be interesting?

Yeah, it's a prequel again. It's supposed to be the first chronological chapter of the saga, meaning we backtrack even more in the game's timeline. I'd rather prefer that they would continue the story or make a new one, instead of adding to it's backstory in character development and the circumstances that will eventually lead to the ulterior installments.

It's somewhat limited to keep treading the same prequel grounds, because we all know the story cannot expand in certain ways. By the end of the game, we all know where Kratos will be and who will be left dead or alive. I may eventually play this game since the gameplay looks awesome, but I am somewhat dissapointed that they didnt take the story elsewhere.
