Civilization V recently got a lot more holy with the Gods and Kings expansion, but some of you fence-sitters haven't yet indulged in abusing religion for your own selfish ambitions. If you're still itching to give your theocracy a try, you'll be happy to know that a demo for the game is now available.
You can grab the demo from Steam and give it a try. The expansion adds new civilizations, religion and city-states, new wonders, new scenarios, and espionage. It seems like a pretty hefty chunk of Civ for $29.99, but the the demo is one way to test the waters for yourself.
