Lots of fun. The only video I was able to make was a few brief moments showing the exterior of the bar we played the game in, and some of the fansite guys. I don't see the harm in posting that, I'll upload it in a bit.
There was no way I was going to get any video inside the bar. There were enough cameras inside, I'm sure those pictures or video will be posted sometime soon, though they had nothing to do with us. They were Rockstar's/Xbox's crew.
But more importantly enough, the addition is really good, and I don't think I'll be killing time on GTAIV without LaD enabled from now on.
