@Rikatah: let me turn it around, IMHO you answered it yourself.
Do you really think an MMORPG could be the ultimate catalyst in someone committing suicide?
What could really be a strong enough reason for an online game to even put the suggestion of suicide into a gamers head?
[Another] reason is maybe a "SOFTWARE GLITCH" makes a player lose years and years of effort put into a game.
People do have problems. Some people have worse problems than others. (Whatever the specific problem may be, medical/mental/emotional instability reasons etc). So sometimes all that is needed for someone to be pushed over into thinking about or actually committing suicide is some kind of, well... for a lack of a better word, trigger.
Could something like a "software glitch [that] makes a player lose years and years of effort put into a game" be such a trigger? Yes. But on the other hand, about anything "bad" happening to such a person can be.
So in the end, you cant blame the trigger for the underlying problem which is something entirely different. people like those from the link would have needed help way before that - and to do that, someone who noticed that they were in need of help.
