I tend to resign when the game is fairly hopeless both IRL and on Isotropic (I might even resign too early sometimes). I have no problem with my opponent resigning if they are losing, but several people I have played recently seem upset when I do resign. This is in spite of saying things like "Good game ... very nice deck" and so on. My son when we play in real life also becomes annoyed when I resign.
I understand wanting to see your megaturn go off and so on, but why would you respond with scorn if your opponent concedes your deck's superiority?
I wonder what everyone else thinks: should you sit through a clearly lost game? Is it rude to resign? Or is it okay to resign so you don't have to sit through until the brutal end?
This is a valid question, and to me it's simple: In a two-player game, it's perfectly OK to resign when you're sure you're losing. This is a tried and true method of admitting defeat in most traditional two-player games like chess and go. It's considered rude, in fact, not to resign if you're sure you have no way of winning (or reach a draw), in these games. The reasoning is simple: No player can end the game by saying "I'm going to win, so let's just call it a win for me". That really would be rude! The losing player can, however, do that, by admitting that they're beaten. The winning player doesn't have that option, and no player should feel offended if the loser resigns. You still win. He or she can't steal that win from you, even if you don't get to play another megaturn or two.
But this changes dramatically in a multi-player game, IMHO, as it might ruin the balance of the game considerably. Someone may have built up an amazing engine, but might lose because they haven't been around long enough to reap the benefits of that engine yet, while some other player may have their opening three estates and win, despite a clearly inferior deck.
These are just my thoughts, though. I don't usually resign myself (so I would be considered rude in a typical chess community), but I never feel offended in any way, if someone concedes a two-player game with me. They acknowledge defeat and hand me my win. How is that bad?
