My background: Just finished playing my second game of Battles of Westeros. (BoW) I have Battle Lore, (BL) and I am a fan of George R.R. Martin's Song of Fire and Ice series of novels.
Components: Awesome as always. Great production values. Usual heavy card stock components, and quality cards. Art is top notch. Minis continue to be the soft plastic. Minor difficulties mounting the minis. But I made quick work of the model assembly with a modeling knife and liquid model glue. The modeling knife was not strictly necessary, but I found it helpful.
Impressions: The new command system is excellent. It provides a much greater opportunity for strategy/tactics. And the system deals with the swirling maelstrom of combat found in BoW much better than BL's system would have. The combat system has also been updated a bit.
Players alternate back and forth numerous times during a "turn," keeping the game much more interesting. (I used turn in parenthesis, because a "turn" in these rules is a much smaller segment than commonly found.)
The first game we played was primarily to understand the rules. The second game was very close, with the objectives going back and forth several times, right down to the last die roll of the game! Lots of fun.
Conclusion: If you are looking for an upgraded version of Battle Lore, this game fits the bill quite nicely. If you are a fan of the book series, you will find this game an excellent implementation of that background. Overall, I am very pleased with Battles of Westeros and highly recommend it!
