With Rockstar films I deducted that the most entertaining mechanic I could do that didnt require too much in terms of game play was to trigger a Mosh Pit with Crowd Actors (which ended up being a terrible idea).
Crowds are something we discovered last semester during our initial Clowd Control testing the Crowds are a complete bitch to control and there is little to no documentation to support the use of crowds. Nevertheless, I decided to try and give them another shot in an attempt to outsmart the mindset from last semester.
I attempted to keep things simple. Basically just use the Attractors and Repulsors to lure the crowd into the positions I wanted them, and trigger volumes to enable and disable to effect. When the crowd would be attracted towards the Attractors, they would sort of circle around and create what looked like a Mosh Pit. I experimented with different settings to see what kind of effects I could enable them to do. Circles pits, Wall of Death, depending on the location of the attractors and repulsors.

However I came across a couple problems. Whenever the file would open, the crowd behavior would 'freeze' so to speak, and new actors had to be placed. The same thing happens with minor adjustments to their position (sometimes).

So the mechanic would work, when it felt like working. That much can be said about the Crowd in general.
