Very very Great, Peter!
An excellent way (IMO) in adding a very concrete historical and/or exotic mood to the Game, which is already plenty of realism and surprises! Such an improvement would surely be incentive, even helpful, for players who are (or want to be) subscribing more and more scenarios... And detailed, formative & suggestive AARs, too!
