Im on the fence for this. I know whenever I play CS:S I end up getting more mad about seeing a "gg" misused than when I play Cod4. In CS:S, you'll end up playing a map thats hevily in the other teams favor (assult as an example). So almost any and all attacks are usless. And by the time the map ends, I've been killed by the same camping awper about 10 times. Now, when he says "gg" I get mad. He was sitting doing nothing for entire map. I had to act like 007 and try to figure out a new way into that building without being seen, only to be shot. The fact that he thinks sitting in one place and killing me before I have my head in the room is a good game. It's not, it's a bad game. If he were to move and come outside and we had some close gun fights, I would've thought it was a good game.Now when I play CoD4, I never run into this problem. It might be that I've always played on a server that the teams are dead even. You never run into the problem that someone is just sitting somewhere. So by the time the map ends people have had close calls, good saves, and great kills. So to wrap up, in situations a "gg" in not acceptable. When it feels like you're shooting fish in a barrel, do not say "gg". But when the game has been close and you're running to get somewhere to help a member of your team, then please say "gg".
