This is just a silly picture of me (left) being hunted by a love sick succubus (right).

This image is actually based on one of many, MANY, roleplay sessions me and some friends did.
But unlike D&D, the creator Sandra Lindblom set up some very simple rules which made it more funnier.

1: The play requires that each player should have only have one 20-sided die. The Master must have two, one for the play and one for the player.
2: The game requires 2-4 players and one Master.
3: When in a situation created by a Master, the players should react how they would react in real life. Which means that no players shall create their own character, they are their own.
4: Snacks. Can't play without the snacks and the soda.

When the game starts, when the players are being sucked in a world of the Master's choice, ther must remember two things.

One is the dice. In a situation where you for an example are under attack by a monster, and you have to fight him. The player can how many throws they can, as long it doesn't slow down the game or the Master is simply a jerk and kills you. In any case, the higher the numbers are, the more luck you have towards victory. The Master however must throw a dice for the enemy on how much they takes the damage and or they counter strike.

When you and your friends are in that world created by The Master, it's you who are in that world. You are not a 12-level Elf Archer, you are youself. So when in a situation, you should act like how you would react in real life.

Two is the Master. He or she is responsible for everything that happens in the game. The Master should be not only able to play several characters the players are meeting, the Master must also be creative and not stay in a linear path. Because the players may be doing something that the Master can't quite expect, so be ready to have a reservation plan for anything. Or simply improvise.

The Master needs to remember that this game is not about killing your players. The trick is to keeping them alive as possible, so if a player are in a grim situation in which only death could be the only solution, the Master must throw two Lucky throws in order to create a situation where the player finds rescue by any means. But if the player dies in the game, doesn't mean that he can't return by some way of another.

One last thing: THERE IS NO RULES. BREAK THEM, IGNORE THEM, the point is not get experience points or whatever, the point is to have fun.
