Great article from Blackline Simulations, one of the world leaders in realsim events:
Do yourself a favour and give it a read.
Some time back I had the pleasure of being a remote observer at one of these events. Even from the distance the U.K. is to Canada, it was immersive and compelling; highly professional in terms of event planning and management, and involving highly focussed participants.
These Canadian guys don’t fuck about.
