I just played in the Chaos Marauders Event at Gen Con and it was a blast! It is definitely a beer and pretzels game, and I mean that with the highest adoration. Fast, simple and chaotic: it's everything a game about Orcs & Goblin tribes battling for supremacy should be. All of us enjoyed ourselves and can't wait to play again. It's simple enough that I will be teaching 9 & 12 year olds to play. The classic GW artwork is a blast from the past. The production values are typical high standard FFG.
A word of caution though, it is a given that you must play the game with a sense of humor. The chaotic nature of the gameplay can make you king of the hill, and then strip you down to nothing. I know firsthand.
Enjoy!

You guess at how long your line might end up. You draw to fill the line. You hope to randomly acquire all of the parts to multiple piece siege engines. You DO make a choice when your line gets to attack, but it tends to be painfully obvious what will give you the most. It's nearly totally random, but some people like that sort of thing.
