I wonder if the word honour is appropriate, and yet I think I know exactly what you mean.
I agree with what Oneway said that it is symptomatic of the results-centred culture which tends to prevail. In other words the way you arrived at the result is nowadays meaningless.
In Aces High this announces as people attacking damaged aircraft, three and upwards fighters simultaneaously attacking one enemy, people running to ack to solve their ACM problems and then coming out for the 'kill' when the opponent has turned away or is already engaged, and so on.
I think Guppy's post is very wise. If you really believe that 'honour', as you put it, is important, then act according to your beliefs but do not expect others to reciprocate as this path only leads to frustration.
Perhaps it is a difficult but worhy endeavour, to value your reputation more than your own score or ego?
