I played AMTL v3.11. My army was:
Warlord - 2 Quake cannons, a Volcano Cannon, a Carapace Landing Pad and Legate
Reaver - 2 Gatling Cannons and a Laser Burner
2 Warhounds - each armed with a Turbo Laser Destructor and a Vulcan Megabolter
1 formation of Forge Knights
1 Serf Levy
2 Thunderbolts
Game I:
I played ePilgrim's Demiurg. This was my first game ever against Demiurg; so, I didn't know quite what to expect. It was also my first game with AMTL v3. Demiurg won 3-1, but it was a close game that easily could've gone either way. For some reason ePilgrim had a strange fear of my Warlord

As for the Demiurg list, I gained a healthy respect for its air assets and it didn't seem overpowered.
Game II:
Another game of firsts. This time I played Dark Eldar for the first time. For this game, I was the one with an unnatural fear - of Dark Eldar in general, due to my unfamiliarity with them. Even though Moscovian won, I held my own. We came down to points and as Moscovian mentioned he won by a measly 100 points.
Game III:
Since two players couldn't stay for round III, the remaining four of us played a fun game. It was interesting playing with someone with the same army, but not being able to communicate with my team mate. Having played against Dark Eldar only once, I really had no idea how to play them properly. Moscovian was somewhat unfamiliar with playing AMTL, but Dave has played against it enough. Epilgrim and I lost horribly, but it was a very entertaining game.
Sunday:
Another entertaining game. We played on a 6' x 8' table with each player starting in a corner. To my left was Mosc's Necrons, to my right Dave's Marines and on the opposite corner ePilgrim's Demiurg. I played Knights with two Reavers in support. The Necrons had roughly 7k points, the rest of 4k each. Dave pulled out the win with excellent tactics.
Thoughts about AMTL 3.11:
I really believe this list is better than 2.0. My opponents would probably agree. I like the structure of it, but it would have nice to be able to have three support formations so that I could have spent a spare 100 points on Sentinels to get an extra activation, rather than spending it on a Titan. Now that I've played v3.11 a few times, I'm looking forward to playing the Tech Guard list.
