Why ? Argentum Age is a digital collectible card game with tactical elements and a focus on skill. We aim to be a community-driven game that is developed by and for its players. The game is Open Source and is designed to be moddable. We are also committed to Argentum Age avoiding any “pay to win” elements that some games feature. The stable version may be a bit old but they are still developping the game.
