To be fair, RicardoRix said "it
sounds like a 'me me me' statement".
Which I interpreted as, "perhaps there are other interpretations, but that's how it comes across."
The statement being analyzed, if I am not mistaken, essentially comes down to, "One or two minutes of my time is more important than a possibly lengthy list of reasons why one or more people might benefit from having the end-game state shown and the end-game stats displayed." It also omplicitly is saying to the other person, "I don't care about the end-game state or the statistics, so it means nothing to me that
you might care.
Which does
sound like a "me me me" statement.
If someone legitimately cannot spare that one or two minutes, well, okay. But I doubt that is the case more than a tiny percentage of the time, if ever.
And in general, I believe it is to society's detriment if everyone were to take that approach.
With regard to agreeing to finish the game, I surmise RicardoRix was referring to the BGA code of conduct, which says a player should not "leave a game in progress on purpose". That's a bit hazy, but conceding, especially right at the end but just before the game actually ends, could be construed as "leaving a game in progress".
On a personal level, I perceive an agreement to play a game to have a built-in agreement to play the game to completion unless there is a good reason not to.
And, "I don't feel like wasting a minute or two of my life" is ... a reason - but, from my subjective vantage point, it is not a
good reason, and I believe it would be viewed as poor sportsmanship if done in person, unless it is a situation like an imminent checkmate in chess in which it is customary to lay down the king when the opponent has a clear win. Even then, if the opponent said, "I didn't even realize I had a winning position, could we play a few more moves", I would have no objection.
On BGA, I can recall two galling examples of someone conceding right at the end.
1) The opponent was explicitly rude in the comments while doing so, and it was clearly poor sportsmanship based on what was said.
2) The opponent seemed to be in no rush, allowing me to play out my final turn even though the outcome was decided, and then with one more left (of mine; no further action was needed by the opponent), the opponent conceded. Finishing the game would have taken no extra time for the opponent. It was a real-time game that was 30 seconds away from being over, and if time were the issue, the concession could have been done a lot sooner rather than wasting both players' time and still not having a complete end-game state or statistics.
I've played many games, and in many of them, the outcome was clear before the final few turns, and yet both players finished the game. SO, on some level, there seems to be a societal understanding that finishing the game is part of good sportsmanship.
Which perhaps increases the extent to which it comes across as poor sportsmanship when the game is conceded right at the and.
