Most of it is filled with the 50-person spanish events, which are cool, but watching them really makes it clear how far SC has to go. Rubber banding, lag, out of sync, etc. Impressive that they got it coordinated and worked around the bugs, but I bet CIGs servers were screaming in pain by the end of it 
OK, the grip stuff is cool. It’s a level of detail I’ve not seen other games do, or even attempt. Most games just force everything to be the same so they only have 1 grip and that’s just it. Nifty.
This is so cool, so seriously cool, and so important to anything resembling group play.
