Given the general reaction online, Zig, it would appear that you are wrong on both counts.
I'm not sure why it even matters, though. Video games aren't something most people play for the story. It's the gameplay that ultimately matters. If you want a good story, there's almost always a far superior story available in nearly any book you'd care to mention than you'll find in the best of games. That's because games require so many different elements to bring a story together in a meaningful way. The whole "Play a game for a while, then watch a cutscene, then repeat" angle doesn't work. The more of that sort of thing a game includes--in an attempt to tell a better story--the worse the game becomes.
The games that really let you play a role in the story tend to have very little scripted action at all. They're something like the Elder Scrolls games, where you largely make your own story, or they're (from what I hear) something like a Bioware RPG such as Mass Effect, where your choices have consequences that carry through, or they're The Witcher 2 or Heavy Rain. That kind of stuff is difficult to do, and expensive, and you often have to build your whole engine around it to make it work. So with something like God of War, story can't ever reasonably be the primary draw. As long as you're able to gore monsters and whatever else Kratos does (and as long as it all is fairly intense), gamers are going to be satisfied.
Besides, prequels work for a reason. Even when people already know a story, going back to it in fuller detail is always a temptation.

"What if everything you see is more than what you see--the person next to you is a warrior and the space that appears empty is a secret door to another world? What if something appears that shouldn't? You either dismiss it, or you accept that there is much more to the world than you think. Perhaps it really is a doorway, and if you choose to go inside, you'll find many unexpected things." - Shigeru Miyamoto on secret doors to another world
