After a while of playing pathfinder, our GM decided to start a new story and are making us use the point buy system
He is however saying that we have to purchase races with this system so that by using the 15 point system so that if you want to play a human you have to pay 10 points for playing as a human, and have 5 points left for adjusting your ability scores.
I however do not find anything in the rules which support this.
