I'm not sure it attracts a significantly higher amount of "people who have a difficult time in reality." You don't know the person on the other end of WoW or Xbox Live. People in other activities might be just the same, but go unnoticed because they may just be written off as "quiet" or "loners."
What I think happens is that they are noticed more in fantasy role playing because it is by nature a social activity.
