I would rather my opponent concede the moment the loss is inevitable and unavoidable than wait until I am literally making the final move and the end-score screen is about to pop up and conceding right at that moment. In that case, it was just a waste of both players' time.
Conceding isn't really an issue. The issue is "quitting" before a concession is allowed, which, for some reason, only awards a partial win to the winner based on "how much of the game has been completed", which seems rather arbitrary. Most games do not have an easily identifiable "progress percentage" to use for this purpose. Also, a win should be a win. If a player quits because of a bad start, the opponent should get a full win.
