You might not have seen in before, but Hannibal: Rome and Carthage has a new demo available, so you can try before you buy.
The new demo coincides with some of the updates that have been made to the paid game - such as improved tutorials and a more balanced AI for newcomers.
The game itself is a turn-based strategy game that puts you in command of the Carthaginian military during the ancient era of Rome. Play consists of two layers - the first is a strategic layer where you maneuver your way around the political intrigue and military units. Where your units run into the enemy you're thrust into a separate battlefield, where a "simple but engaging" battle system will decide the victor.
