I was playing capture the flag in minetest when somepony on the other side messaged me "team?" I told him what? but he wouldn't fight me for the whole game and he kept saying sorry whenever he hit me. After that I won because he just let me take the flag with no resistance. The victory felt hollow because the enemy team didn't give its all so I stopped playing. I felt dirty having such a player on the server. I should have told him to fight for his team with honor rather than act as a double agent for the other side.
