It looks a lot like Crackdown 1 and that was a lot of fun.
I think a lot of people in this thread were practically born yesterday and have never played that game. The hate gets contagious and people think they have to ride that train.
From the people that hate what they see now, i think at least 50% are just echoing others.
The destruction is probably what will kill this game. If it's not what they promised it will be the only topic. That's totally on them though. But the rest of the game might still be a shitload of fun.
I agree about the hate being contagious (the hate and the worship for most games are contagious through gaming forums).
But I don't think that a disappointement about what they have shown is unjustifiable. The animations are bad, graphics are just ok because they're cell shaded (which helps to give it a better look), there are some serious pop-in issues, and the gameplay presents nothing new nowadays. When Crackdown 1 was released, destruction mayhem in open world games was kinda of new... but now we live in days which open-world games are much more common and enhanced, including others with similar intentions (such as Just Cause 2 / 3 and Saints Row 3 / 4).
That said, maybe the game doesn't look a disaster, but I also see absolutely nothing that justifies a hype above avarage for this, other than carrying the name of Crackdown. Not nowadays with so many options, not with the pointed issues, not for 60 dollars. At least not the campaign (we will see about the MP).
And about the destruction being always for multiplayer, I think they failed in spreading that message. I just knew about the destruction being exclusive for the multiplayer after this E3 presentation, when some people started saying that it was no surprise. I participate of different Xbox communities where people was also surprised with the lack of destruction in the SP mode. I'm not saying I don't believe it was always like that, but maybe by the fact that they used to talk about this game just to talk about the destruction, I could swear this was part of single player mode as well.
