It's a 2-player deckbuilding game on the First Punic War, i.e. the first big war between Rome and Carthage. So, not Hannibal, but Hannibal's father, Hamilcar. The mechanics are heavily inspired by a game called A Few Acres of Snow, which in turn was heavily inspired by Dominion.
This will be my first game published in 5 years. Too long, but the amount of time I've put into it (being mostly unemployed during that time) has really allowed me to hone the game.
