I just created an alt and they automatically started with all lowlands while my main (this one) still have to pay for the lands.
You are getting the new player perks. It started as a temporary promotion to get new players to join but the devs thought it was a good idea to keep it around so they made it permanent. This only works for new accounts made and older players cannot get the perks. Locking thread now because OP's question has been answered.
