Maybe not a quick rundown...
I saw the ad for it on the Condottiere SilverLine FFG game and bought it because it looked cool. There are lots of rules to get around to, but by playing it a couple of times you'll get the flow of it. It kind of is a given that you get high quality cards/pieces/board since it's FFG, but the game itself is the real winner IMO. There are no dice in this game, with decisions being made at random with cards. Every player gets different cards which dictates what you want to do, then you put two cards (or three) into three piles and the other players does the dame. Shuffle each pile with the cards chosen by your opponents and the random "neutral" cards that the game requires. There's your round. When the three piles are gone the turn ends, and you collect influence.
I don't understand how anyone manages to play this in less than 3 hours though. It is a long game, and we might have played a game for 7hours even. But that's just my experience with it. It only was short one time because we misunderstood the rules regarding when to pick up influence. We thought it was after the first pile of cards was drawn, but it's after the 3 piles are drawn, which f.ex concludes round#1 finished.
Other elements in the game I like is going on random explorations to far away lands, where you either lose all the gold you put into the exploration, or you get lucky and almost triple your gold.
Assembly is also pretty nice. You have a certain amount of votes that you can use to get certain "laws" in your advantage. Of course if there is something in particularly interesting for all players, the one with the most votes for himself gets the "law". I can't think of a better word than "law" at the moment...
Then we have warfare, you can conquer cities and build fortifications, hire armies, and of course attack other knights. But it's more "political" than that. As it says on the Warrior Knights site "Warrior Knights is a game of medieval diplomacy, politics, and war."
Also the card element is pretty brilliant. It's always randomly chosen what will happen in anything you do except on laws you vote for. Oh, and you also get certain faith points which you can use to f.ex bless your sea exploration team.
I really don't know how to better explain it. I think it's a "the more the merrier" kind of game as well. I've only played with 3, but you also can be 6 people. I'd definitely try that out if I got hours to spare.
No dice, no need to write notes, everything is in the box. All the faith, votes, cards, armies, influence +++. Easy peacy Japaneasy
And the expansion makes the game even better.
