My Favorite is Battles in Normandy by SSG. It's a great old fashioned hex style wargame , easy to learn but full of Strategy and with an AI that will give you a run for your money.

Keep up the reviews of Cardboard games. I really like to see what going on with them also. I find that I am a sucker for solo games.

I purchased Sans Allies solitare game over Christmas. It's a takes Classic solitare and gives it a wargame spin as you try to defeat the enemy before he develops a super weapon.
It's a quick fun game ..

I would like a key!!
