In any instance, this video covers the basic over all story of the game, The Civil War aspect at least. There are hints as to something else going on to make the game more than just a political argument between all the heroes. Although it would be interesting to see a choose your own adventure of this. I want spidey to swing over and tell Tony Stark to screw off instead of joining up. Select X to choose this option. Then watch the new story arc. Maybe it is just me.
I will say that from this video, I did see a few things that make me even happier with this game. Like the inclusion of what actually started the whole sheBANG. Fans know what I'm talking about. Not a fan? They watch the video here and play the game when it hits selves.
