You think I bought gil? No. I hoarded my gil and built it up over time to buy a large mansion for myself. It helped that the semester for college ended and I could play all day long when heavensward came out and prices on all the gathered mats were super high, but I spent a lot of time acquiring the 40 million gil for my mansion. There are actually people that have earned hundreds of millions of gil in this game. There are even people who have multiple houses by having their own fc house and a personal house and/or having multiple alt characters.
