The creator of Ultima Online (Richard Garriott) was killed in a beta test of the game while he played Lord British and giving a peaceful talk to players of the game ... or something like that, he was supposed to be indestructible but someone found a way to beat him.

I don't see the point of people arguing with each other here ... over what happened in WoW, morally it was wrong I guess, but the way the movie of the incident was made and the timing of the music made it funny. Black humour I suppose.
The person who died wont have their real funeral spoiled, this was a game taken to seriously by some IMHO.
For sure, some people are taking games to seriously though, when you look at some of the comments made in those WoW forums after the attack, about wishing death to the raiders fathers, they are all just as bad as each other.

Lot of nutters out there.
