The Game of Kings was professionally organised and run, and the feedback from those who attended has generally been very positive, especially so if people were involved in the strategy side of the game. I have now been involved with three events run by Bluehat. From my point of view, this was the weakest, largely because those who were only grafting really didn't get involved in the strategy of the game at all. I also felt that most of the challenges (the ones I was involved in, anyway) appealed to those with a similar set of skills (logic puzzle-related), whereas the other events you've run for us included much more varied activities, with an element of choice over which activities you pursued, or which team members you deployed on particular activities.
