I really think some people take gaming too seriously. Especially those who pvp heavily. I was heavy into pvp myself back in UO, but except for a few occassions I didn't let things get to me. I did, however, notice that there are a lot who really freak out about little things. This seems especially true of those who really like to stroke their egos.
Ahh well, lighten up people! Understandable to get mad sometimes, but don't let it get to you.
This applies to both real life and gaming... just "chill".
