Ok, so everyone is complaining about the land price. Some idea came out of nowhere while working in office.
Make player can apply for mortgage loan from SE ;););)
fixed land price and dont discount it every 6 hours, we pay in installment for 3/6/9/12 months with gil, if we fail to pay the loan, we cant get gil/seal/tome until we pay our debt.
it can be another type of gil sink with the mortgage interest rate.
