Have you ever participate in an online game? If yes, then have you have any unpleasant encounters with your virtual teammates or anyone in the game?
I have fond and bad memories with various online games. In DOTA, since I played with friends and friends of friends, there were team spirit and an atmosphere of respect. In MapleStory, I had bad memories with people calling me noob when I was already at high level, fully armored with best equipments there are for a magician (okay, not all equipments).
