I guess the only person that I've specifically told is my girlfriend, because otherwise I wouldn't have a straight answer about what I was doing most of the time
I've shared the game with a few of my friends but the fact is, its a pretty niche mod attached to a pretty niche game so a large proportion of people simply won't be interested :p
My dad found out by himself because he's usually around when I loose my temper with the game :p so it and me are usually the butt of his jokes
