I don't even say "gg" when I win the game, why?

[wolffoxcat]

it annoys the other players

it annoys me if the other player won and they don't say gg.

Why wouldn't they think it was good game when the won?
Why wouldn't they want to use a friendly goodbye message?

If you do sign off and you lost, then you get a green-thumb.
If you don't sign off and you won, you get a red-thumb.

To me, it means you played a good game

Because it's like a comment that teases the losing opponent in the game.
I don't know if it's because of the cultural difference with the West because I'm Asian, but in the Eastern Go game, it's a basic courtesy that neither the winner nor the loser of the game express joy or anger.
I don't know if you're saying "gg" because you had fun after the game or if you're saying it's a good game because you won, but I don't see it as a cool sportsmanship.

Maybe you are over thinking, but Win or lose, I try to say "thanks for the game"

One time I said gg when I lost and they responded with "not really"
