Wow.
All the power to him - I mean if I had a trust fund (I.e. didn't have to work) and didn't have school, friends, poker and a gf, I would be a powergamer. If I was a powergamer, I'd be pissed that he beat me to it!
However ...
The fact that this is possible is a bit disturbing. I mean one of the beautiful things about FFXI was that while progress was slow, it was rewarding. When you got a level, you felt like you accomplished something (at least I did). I played 75 DAYS PLAYTIME on FFXI and didn't get near the level cap. I mean I could have been 75 in that time, but there were so many things to keep my busy that getting to 75 was never my prime focus. Anyway .. I guess what I'm trying to say is that if he got to 60 in 10 days, there is no way he has more than 8-9 days of playtime (unless he uses speed in place of sleep). Now - he knows what he's doing. Even if you double or triple that, it's still a hell of a short ride to the cap.
Is it a good thing that the cap can be reached so quickly???
