Gaming the Victory Point Sysytem

Hello,

I am new here, and I started my first game recently. It was a private game with all AI that I wanted to use to study and learn the game mechanics. After finishing up with what I wanted to do, I “claimed victory” to end the game. It was then that I realized that I was awarded a victory point.

I wonder if there is an elegant way to prohibit points being ‘earned’ in this manner?
