Darren, from the UK, is a video game "modder." And he did his thing on Total War a while ago. He added Book of Mormon names and places to the game, allowing players to enter the Promised Land and the battles that took place between the Nephites and Lamanites! Check out this game trailer:

As it is a mod, you will need a copy of Total War with the Barbarian Invasion expansion, along with the mod file provided by Darren, via the Book of Mormon Battles website (link).
On the Book of Mormon Battles page, near the bottom, Darren gives thanks to several who contributed to helping him complete the project. It looks like there were a bunch of people who helped out. It's great to see that so many are open and willing to share their talents with others.
Overall, it looks like a fantastic game! I really need to get a copy and try it out.
