There has been some previous discussion about this topic on the forum, but it seems that resignation still rankles. For what its worth here are my thoughts:
I think there is a fundamental disagreement over what sort of "contract" you enter into by agreeing to play a game with someone.
I think this is the cause of the difference between players. Some see it as a binding contract to play until the end of game conditions are met, as jeebus has argued:
According to the rules, you take your turn, you don't resign. By starting to play a game, all players agree to play by the rules.
Why not? Having a resign button is a variant in any case, just like a VP counter. The rules say nothing about being able to resign.
Others like myself don't. I expect my opponent or myself to resign at any time for whatever reason at all. No explanation, forewarning or apology required.
In addition to resignation, players may just leave the game, as jaina8851 points out:
The second opponent didn't even bother with resigning, they just left the table and forced me to wait five minutes so I could force them to resign. Both cases left me inordinately irritated because once the person ragequits, I have no recourse...
I live in a country where it is not unusual to have power outages. This has happened to me a few times during a game. Obviously this will be interpreted as a ragequit by the other player if I am behind and may even earn me a place on that player's personal block list once that is implemented. There is little I can do about that, since hours later, when power is restored I am not even in a position to explain myself.
Mmh, my initial idea was to reward those resigned wins with additional points due to the fact that the victory was so overwhelming, that the opponent even resigns. What I mean is, that a win with a big difference of VP should be more weighted than a closer win with only 2 points difference – so why not adding some points in addition when your opponent is resigning – just an idea for those people like me thinking positive about their opponents.
Isotropic didn't do this and I hope it is not even considered. A win in dominion can be close with a large difference in final vp and very unequal with little difference in vp. The person who resigns, conceded the game and lost and that is all that should be considered.
...the (optional) continuation of the resigned game by replacing the missing player with an AI sounds much better than leaving the remaining player with its half-finished turn.
I think this makes sense in a game with 3 or more players, since more than one person is affected, but not really with 2 players. I don't care about finishing my mega turn if my opponent concedes the game.
