Last time we played Risk, I kept babbling about The Three Kingdoms and how Zhuge Liang would have handled this and that situation. We ended up with me in north and south america, another player in australia and half of asia, and one player in africa, with nobody really caring about europe. Kinda like the Three Kingdoms. Then the guy in australia and asia attacked both me and the guy in africa simultaneously, and somehow scored successes against both of us (including taking half of north america (I later found out that north america and australia were his mission)). Kinda like Wei. Then I placed an entire round's worth of reinforcements in china and took the topmost territory in australia, causing him to abandon his north-american campaign in order to win back australia. Attacking behind the lines ftw. Thus The Three Kingdoms helped me to my first Risk win ever, about ten rounds later.
