It is difficult coming up with them all. I have a fair list going, however. I'm wondering if it shouldn't be busted down to three situations instead of four, since the situations you've been trained for are more useful than the situations mice have in their nature. Gathering intel vs. foraging?
EDIT: No, I haven't seen Realm Guard. What is it, retrofitting Mouse Guard to high fantasy?
EDIT EDIT: I was also thinking of letting the Tactics skill mirror Weather Watcher, by which I mean if the player beats a high Ob test, he can predict or trap opponents into using specific tactics, which the group will then be ready to counter. Thoughts?
