Sometimes when I am playing a game and my opponent has over 40 prestige and there is no way I can tie or exceed that I will concede. The reason is that some players will spend over 5 minutes playing card after card when they know they have won the game. Why prolong it? They should end the game when they know they have won.
I also don't think conceding should have a penalty attached to it. All conceding does is show the opponent that we know they have won the match and concede the victory to them. Why punish the player for admitting to their loss?
