I think its one of the best, it was amazing, epic set pieces, awesome environment and we didn't even see the full intro. The last 1 sec of the video showed much bigger things to come. I definitely restored my faith in the game.
Also, I remember in early reports they said it was going to be the shortest GoW game but now on the official site it says the length will be comparable to GoW3. --- |--|o\/o|-|~ Can't let you do that, Star Fox!~~~| |--\_O/--|~~~~~~~~~~~~~~~~~~~~~~~~|
It's a GoW intro, so it was never going to disappoint. I still think GoW3 was the best. The assault on Olympus with you and the Titans waging war, everything was leading up to that moment, it's the very definition of epic.
The length really shouldn't be a problem, as long as it's around 8-10 hours I'll be happy. --- May the odds be ever in your favor http://i.imgur.com/C41sDRQ.gif
