Rolled 8, 5 = 13 (2d11)

Try "dice2d11" and you'll see.
Sounds like my opportunity to implement something with deciding the entire outcome of a battle in a single roll, flanking/frontage/"combat width", operational and strategic reserves, blitzkrieg/deep battle, terrain penalties, a small degree of logistics, neutral states, uprisings and resources.
Though I'd rather have something that can be played slowly over weeks. With simultaneous orders like Diplomacy absentees aren't a problem, with a player order each player gets a time limit on his turn.
