A friend of mine told me about this game he is in, simply called Assassin, and I thought I'd share.
The rules are these: you get about 30-50 people, most of who don't know each other, and give each of them the photograph and name of someone else in the group. That becomes their target. Now each player has to find and "kill" his target. By the way, this could go on for months.
Two good kills:
1.
There was this guy who went out to drink beer and have a good time with his buddies one Friday evening, and he picked up a goodlooking girl and brought her home. He poured them both wine, and they chatted and flirted for a while. He went to the bathroom. When he got back to the livingroom, the girl was gone, and in his empty glass was a note saying "You have been poisoned."
2.
A guy was walking down main street in our town, when he suddenly spotted his target in a phone booth. As luck would have it he was carrying around a fake but realistic-looking machine gun in his bag, which he was going to use in a roleplaying game that day. Immediately he grabbed the gun, dropped the bag, and ran toward his target, firing blanks: WHAM! WHAM! WHAM!
A few moments later he was lying face down, handcuffed. A police car had been parked nearby, and the cops tackled this maniac and disarmed him. But he did get his target, who had lost all the color in his face there in the phone booth.
