I also like the game system. In order to move and attack you have to play a card from a hand. The card you play tells you which units on the board you get to move that turn. I like this mechanic because it causes you to have tough choices during the game. Your actions are a finite resource and you must manage them carefully. I also like how the scenarios of the game start out simple and them increase in complexity. The first scenario uses only infantry and then the game slowly adds, artillery, tanks, special units, and so on. The only complaint I have about the game is that it uses special dice which have symbols painted on the sides. I always prefer my dice faces to be engraved.
Memoir 44 is simple and you can easily play a couple of scenarios in an evening. It is perfect for introducing casual gamers to historical wargaming or for a beer and pretzels night with a die hard grognard. I highly recommend it.
