The Centre for Applied Strategic Learning (CASL) now has three wargame-related lectures posted on its site, including talks by Phil Sabin and Peter Perla. Here is a link to the CASL page.
There will be another lecture on Jan 24th on the topic of strategic wargaming, and this can be followed online in real time if you register in advance. If interested, you should contact Ellie Bartels or Katie Dusek via the link above.
If you can't participate online, you should still be able to find the audio on the CASL site at a later date accompanied by some video or Powerpoint materials.
I've enjoyed what I've seen / heard so far!
