Are you or have you ever been signed up for a "game" without knowing how to play, your permission, ever having heard of it before or even ever having been aware of it and it's current and active incarnation?
Yep! My first game playing airsoft, I had no clue what was going on. My friend drove me to the arena with him, threw a gun in my hands, and told me to have fun. It wasn't entirely without my permission though.
