I am not a war-gamer (at all!). However, I love this game.
The way that the card draw, the different uses for each card during play, the ability to draft new cards into your deck, and expand across the board all combines into a very satisfying experience.
One note: DO NOT read anything on the "Halifax Hammer" strategy. Knowing the strategy will rob much of the beauty of the game, and to be completely honest, you would never realize an issue until after dozens, if not hundreds of plays.
