I haven't gone through the 96 or so pages of this. Let me see if I'm getting this right. If I'm wrong, someone correct me on this please.

If I grind 7 days a week for 5 hours and get what... 20k gil a day, I'll be able to afford a house on a small plot.

20,000 x 90 = 1,800,000 gil

So that's not even enough to get a small plot on Balmung.

Unfortunately, some of us don't have 5 hours a day to spare. We have jobs and other things we need to take care of. So for us, this 3 month deal will end up being 5-6, maybe even 7 months...
