Saving and sharing movies multiplies the fun factor by about ten billion. You can download a movie from your friend while they are offline(!), and move and pan the camera around the entire stage during the clip, follow any of the characters you choose, zoom in and out, etc. It is fantastic. The game saves a recording of each match you play (I think it stores the last 15 matches or so), so if you hit an amazing headshot or something, you just load the video of that match afterwards, find that particular moment, and save your clip. You can then upload your clips (or screenshots, or game variants, or whatever) to your shared folder so your friends can download them whether you're online or not. Very slick for a console game, I think.
