vox, I think you're missing his point. How many times in bridge or chess have you sworn at the other player, or just walked away from the board without saying anything to call a draw / resign?
Rage quitting isn't conceding, if you tell your opponents GG and let them know you're leaving, then you're being a good sport.
If you just hit alt f4 then you're upsetting people and showing bad manners, same as if you walked away from a game of chess mid play without saying anything and never came back.
Vox didn't say that at all, and I have to agree with them 100%.
When I used to play chess it was considered poor sportsmanship to continue playing if you were in a very disadvantaged position. You conceed, take the loss, and start a new game.
Vox said the game needs a 'conceed' option, and that's nothing like 'swearing at your opponent and walking away'.
Forcing people to play out another 10+ minutes to mop up is pointless, regardless of whether that 10 minutes is mopping up an AI, or mopping up another player.
If your opponent is several levels higher, but losing ground, they might see a chance to come back, and continue playing.
If they're losing ground, several levels lower, and don't see a chance to turn things around; it's polite to offer a resignation; but it should require the majority of players on the losing side to agree, and the majority of players on the winning side to accept it.
It'd save a lot of hassle for the polite players, the solution for 'quitters' is a different matter.
