I've always thought that BOA would make a great campaign system for miniatures battles.
What would be required would be to allow the option to resolve combat outside of the computer game, and then input the results back into the game.
For example: When combat occurs, you're given a choice: #1 resolve combat normally #2 resolve combat manually. With option #2, the computer doesn't resolve the combat, but rather prompts the player to input the results of the combat. Then, the game resumes.
Any modders out there have any idea how difficult this would be to implement?
