I got to play this evening at the local gaming get together, played Slaneesh. If you looked at the point totals, I came in 3rd. In actuality, I came in 4th.
The game ended in ruination with Tzeentch taking a 1-point victory over the Rat, both of the experienced players. If it hadn't ended that way, the race was on between Khorne and the Rat for Dial Advancement victories.
Khorne was played by a player that had played it before and was trying to learn from his previous mistakes.
Nurgle got bogged down in Tilea, and spent too many resources trying to count on getting both cards into the area to turn it populous, and was basically stymied at every turn by Khorne or Tzeentch.
I had nobles in Bretonnia and The Empire to play for, and I made the error to focus on Brettonia exclusively rather than try and hold both. I was left alone for the early turns, so I could have made a better play there. I probably picked the wrong upgrade, taking Rise to Glory as my first and only taking the Daemonettes upgrade as my second.
The end turn was close, as everyone wound up in The Empire for a massive battle, and I became the late target to keep me from getting first place in the corruption total.
It's an interesting game, but I don't know that I'm quite sold on it as a whole. I definitely need to play it a couple more times to determine if it's something I like enough to keep coming back to
