Sun Tzu famously wrote, "It is said that if you know your enemies and know yourself, you will not be imperiled in a hundred battles." This puzzler draws its inspiration from the game that likely has more than half of the PC gaming population enraptured right now: Civilization 5. Test your knowledge of the game (and maybe a little history) by matching the following civilizations with both their leaders and one of their custom units. You'll pick one option from each column and hopefully come up with matched trios. If you find your knowledge is lacking, direct your advisor to page two for a full briefing.
