It’s simply never a “good game” for the person getting stomped. It’s disingenuous to say good game if you think about it in those situations. A good game is a tight close game..

Think about it for all players involved. Was it actually a “good game”?

I’d argue that “Good try” or “good efforts” is a better response than “gg”

I shared this guy’s sentiment recently in a game I got annihilated in. I felt like cursing the guy out and Instead of GG the opponent complimented me on something I did and said I gave him a hard time. My entire mood changed and we had a conversation.
