Well it is a good warning to keep in mind that you can lose a lot by becoming addicted to a game, without getting real pay off in the end.
In my personal case I failed my study due to a game addiction (well and the study turned out to be the wrong one for me), but in my case I managed to salvage the debris that I call 'life' and I'm making something out of it, though it's taking longer as intended now.
Still, I'm doing quite okay now and I've got a good plan layed out for the future.
I also know of guys who are in their 30+ now and are still working for minimum wage, doing crappy jobs with contracts that they can lose any day and usually don't last more then 6 months to 2 years.
I've also read about how a guy lost his job, his family, friends, house, car, dog etc. all because he became addicted to WoW.
I've also seen people going into a total panick when I suggested that WoW isn't meant to last forever and if they had any plans for what they want to do in like 5 years from now, without WoW. Well this particular guy has a rich dad, so he'll probably be fine in the end, but working for his own money didn't seem to be part of his plans lol.
In a way I'm glad that STO doesn't seem to be as addictive as other MMOs are. Personally I don't plan to invest that much time in any MMO anymore. (I used to play at least 5 hours/ day on weekdays, next to my full time job and often 10 hours on weekend days as well.)
Now I cut that down to roughly 2 hours a day at most, occasionally more if it's a new game that I really enjoy or if we're doing a special task force, but I'm not playing as compulsively anymore as I used to. (Playing for the sake of playing.)
