@clarfonthey gg also has a different meaning. You wouldn't say "good game" to concede a match, for instance, you'd say "gg"
@noiob yeah, although that has to do more generally with the way we use written internet speech to convey formality
like GG can be an abbreviation for "get good" but I'd argue that's not the intent here, it's just stating it as a formality in the same way people say "thanks" for things they don't actually like
@clarfonthey I mean yeah, my understanding is that it's how you formally concede a game of Starcraft
@clarfonthey p sure it developed from telling people "good game" after a match
@clarfonthey I don't think it necessarily can't mean "good game" anymore either. Sometimes you just gotta hand it to your opponent
