Why is it incumbent on the loser to offer to shake hands first? Why is it seen as poor etiquette for the winner to offer their hand first?
It is not. This is the first I've heard someone suggest it is. If I am in a typing mood, I'll say gg win or lose, first or second.
I (almost) always immediately type gg after the match, win or lose, without thinking. Maybe not if my opponent was a bit of a jerk, but that virtually never happens.
I feel most conflicted when it's a blowout. If I'm the loser, I'll say something like "gg. I played that stupid". If I'm the winner, then while I will still quickly type the gg, I'm aware I could be misinterpreted as mocking my opponent. I mean, it's not a good game if they pick a bad strategy that fails hard, but what else do I say?
On very rare occasion, I'll drop a 'bg' (for bad game) in a half-joking manner. The only 2 reasons I can think of for why I've done this are 1) it was an incredibly boring, sluggish game or 2) My opponent was a victim of some extremely awful luck. I'd never say bg if I'm the one with bad luck, that's just whiny and pathetic.
I think gg after the game is fine coming first from the winner or loser. The one thing I do find obnoxious, though, is if the person who is about to win takes time before the game is over to say gg, either at the beginning of their turn or during the buy phase. I think that's reasonably interpreted as mocking.
Oh, really? I don't usually do that, but when I see it I think of it as a "fair warning" type of thing, and making sure they get it in before everyone leaves the uh game room.
(Also sometimes the
losing player says gg early, thereby alerting the other player that they can three-pile on this turn for the win, which they otherwise would not have noticed.)
I have only seen bg a few times recently and at first glance found it kinda rude whether or not the person meant it that way. If they won it seems like it might imply "you played a bad game" and if they lost it's like it was only because of luck.
If I actually think it was a bad enough game that I don't want to say "good game", I'll say "thanks for the game" or something like that instead.
