See, everyone has a different way of seeing things. I find things that seem to be said by rote (which includes the pre-written snippets) feel disingenuous (imo) so I don't say them/use them. I will respond to gg if I see it within an hour of being said (after a turn-based game) - because when people put gg in a chat 8 hours after a game has ended, it annoys me, and I don't want to annoy others - but mostly I don't initiate a gg, win or lose. However, if a game is particularly well played or hard fought, I will say gg because I think it was actually a gg (usually gg, wp actually). It has meaning, there's a point to saying it (imo), and again, this is win or lose. For the most part I prefer not to chat, especially since I mostly play turn-based games which makes the conversation quite stilted (imo).
