Work on the game has been slow (nonexistent) the last couple of months as I prepared a presentation about Biblical Israel. That project has since been finished, and so I will be getting back to working on the game.
The presentation, shared as a slideshow, chronicles the Israelites in the Old Testament as they survive through major periods in history. In addition, it also covers portions of the gospels in the New Testament. It also contains a large number of maps to help visualize the information. The slideshow can be found here.
