FFXI is my first and probably only MMO I will ever play. The day I've started playing it, it went from casual gaming to addictive to time passing activity to social interaction. It undoubtably had profound effect on myself as an individual and my outlook on people in general.
The whole arguement "this is just a game" is played out. I'm not gonna use Ryany's post, because from my point of view it's cynical and obsessive observation. Imo it is a game, just as Soccer or Baseball are games. With 1 difference. You're not facing the opponent under cover of internet annonymity. Annonymity does provide an escape from any form of moral obligation towards fellow gamer, but that only proves the fact that some, not all, people are just assholes.
Kasber brought up a very good point about age diversity in MMOs. With that in mind the values each generation were taught vary and thus represent gaming style of each individual.

How FFXI affected me in real? Let's just say I don't spend on alcohol and recriational pharmaceuticals as much as I used to.![]()
