Well, I've sent 31 people this way to buy OOTP that previously didn't know what it was. They've all bought one or more copies since version 3.
I feel as if I've fulfilled my duty.
Not saying I won't refer more... but most of my core group of friends and family know about the game by now. I'm not about to pull out a bull horn and go around screaming it for all to hear.
Be hard to play _my_ verson of OOTP in a straight jacket.
