Jon Shafer's At the Gates

At The Gates is an empire building game. If you're not familiar with the genre, Sid Meier's Civilization is a good example. You start with a small tribe and have to explore the world, exploit its scarce resources and eliminate or outwit potential enemies. The choices you make start out simple, but become increasingly complex until you control a powerful economic and military powerhouse. Over the course of a single game, your tribe migrates to more lush and fertile areas, conquers and trades with other clans, collaborates with the Romans, learns from them ... and finally destroys them. Along the way, you'll have to master the art of war and make cunning plans to strengthen your kingdom - all while enduring the worst that Mother Nature can throw at you.
