So here's an interesting bit of information...
I've been playing this game since January of 2003. I have taking numerous breaks throughout my FFXI life, anywhere from only a week to one lasting up to a year.
Between my very first character, my newest one, and my mule that I played and leveled for a good while, I have accumulated roughly 520 days of gameplay (and rarely do I leave the game on while i'm not playing at night/work etc..). Now this may or may not be alot compared to some people, but for me this has been a major part of my life.
Now to the point I'm trying to make... So I've played for 520 days. That's comes to 12,480 hours (if my math is correct XD). In the state of Mississippi, in which I live, mininum wage is currently $7.25/hour. So, with these two pieces of information I've calculated that by just making minumun wage in the state of Mississippi, I "could have made" $90,480.00 playing FFXI!
Crazy huh!? Let's see how much money you could have made!
