I play Risk with my family because I like the idea of world domination. It is really fun because I always win. I have the best army, the best home country, and and the best army. Tip: Europe is to be taken at the end of the game because it is a serious pain in the rear. You need to rely heavily on cards to supply yourself with troops. Take Kamchatka early. My forces are unstoppable, I have never lost a game. My superior strategy will destroy you with your sad inferior troops. Risk is really fun and you should play it.
