I see one AAR in that section here in the forums, and I've seen a couple others on social media. But yes, the reason you're not seeing demo agents post about it is they're being kind to the other agents (such as myself) whose games are upcoming. We think it makes for a better game if things like the force mixes and victory conditions aren't known to everyone ahead of time. (Players are given their own victory conditions at the game, but aren't told what the other side is trying to do, just that they're the enemy.)
