The point of the video game was to have a better model for naval damage control than the classic, Star Trek-style "10% damage" that you normally see in naval games. To do that I wanted to model actual WW2 ships, room by room, with the free-surface effect, meta-centric height, etc. respected, and then put you into the role of a DC officer on a ship that was attacked in various scenarios.
That level of detail is impossible to get without these primary sources- and the only people who would be interested in a game like this would be the ones for whom that accuracy is a selling point.
This is just one of my side projects, but it is one that shows the wide variety of projects that NARA II supported, beyond just historians.
