If you've every played Age of Empires or the new Rise of Nations, you've probably realized by now that they are just really elaborate examples of Rock-Paper-Scissors (Pikeman beats Knight, Knight beats Footman, Footman beats Pikeman...). 

Even though I know this - as a 29 year old man I can intellectualize this - but I still stayed up until midnight last night playing International Roshambo (also known as Rise of Nations).  Dammit if it isn't a fantastic game.  I'm not even a big gamer, but the level of detail and thought put into this game is ridiculous. 

Of course, I play the Bantu (my wife is Zimbabwean Ndebele, a Bantu tribe) as they kick the most butt.
