Well, I'm not gonna say he doesn't entirely not have a point.
Sometimes, when playing Halo, if the team wasn't balanced, sometimes I would get into a warthog or mongoose, run up to the enemy who was carrying our flag, and I honked at him until he got on. Then I drove him to our base and let him score.
I thought this wouldn't be recooperated, but a long time later, when I was in the same situation, someone else did the same for me.
It's nice to sometimes have an honor system, because the point of any game is to have fun. Completely dominating a game isn't as fun as a close match, so I can get grey's assertion that letting the other team keep their teleportor as a handicap.
