Basically, we play by "the two rules":

1. If someone approaches you with an action, show a plausible reaction: Play something, anything, but play.
2. When you approach someone with an action, don't expect any particular reaction. Accept what the other person makes of it.

In addition, some conventions apply:

Out-of-game and in-game (German: Outtime and Intime). The entire western town is in-game except for restrooms, showers, saloon kitchen, NPC tent, and parking. All permanent accommodations in the town are part of the play area and are to be used and made available to other players in-game whenever possible (for example, in the context of business, gambling, or a tea party). Please respect if someone does not want to play in their bedroom, especially if the player is taking time off/sleeping. Also, please be considerate of sleeping children. A word of warning: some of the in-game accommodations go out to the main road, so noise on the road can be heard in the accommodations as well.
All tents pitched outside the town proper are not part of the game.

Languages. As German players may want to play characters from anglosaxon countries (and vice versa), when a player speaks another language, just treat it broadly as "another language" without inferring character background.

Hausmarke. Code word for in-game alcohol, which is non-alcoholic out of game.

Silberdollar / Silver Dollars. Code word for Euros.

Masking. Those who are masked cannot be recognized. Masking is essential for robberies or other racketeering. If you put a scarf over your face or wear a mask, you are masked and cannot be recognized. Eyewitnesses to the villainy cannot provide information about the person, clothing, or equipment, but can make a composite sketch.

Firearms. Yes, the weight of a revolver at your side feels cool and we are basically playing make-belief (for adults). But a firearm is the final escalation stage, after which, there is not much room before things become final. We want to encourage players who have been shot at to play hurt, or have their character die. It doesn't feel good at first, but can result in great drama. We'll also help with a new character to get you back into game, we promise!

Pinning. Drawing a weapon and pointing it at someone is already a clear threat. Therefore, we have the "pinning rule": as long as the barrel of a firearm is pointed at you, you are doomed to passivity. The shooter therefore "pins" his opponent. The latter can neither run away, scream, nor do anything except remain motionless, talk calmly (negotiate, whine for mercy, ...) and wait until the barrel of the shotgun lowers... - or a shot is fired! This is true even though the gun may not be loaded.

Misfires in a shootout are to be interpreted as the shooter being hit by a bullet, as many shots are overlooked or overheard (and one can also accidentally have shot herself/himself in the foot)!

Behaviour around animals. Animals are never to be frightened; watch out for horses and cows in play! Do only  enter paddocks with permission of the owners of the animals; but you may feed the sheep with picked grass.

Firearms. We only allow guns that use toy cap gun ammo, both actual toys as well as decorative weapons, but no blank guns or homemade caps. If you are not sure, please ask before the event.

Cutting/Piercing Weapons. We only allow LARP padded weapons, no latex full-cast weapons etc. Decoration weapons that are not to be used in combat situations must be cleared with us prior to the event.

No sexual violence as a game element. Neither as part of background stories, nor as a threat, or game element. This is to protect players who have experienced such things before and/or might feel hurt by them.

Racism/Sexism/religious discrimination. Westerns as a genre come from a time when sexist and racist stereotypes were seen as far less problematic. The genre is a romantic fantasy that was used to transfigure genocide and discrimination into America's founding myth in the 20th century. This is not something we can or want to ignore. Nevertheless, it is difficult to imagine the genre without racism and sexism: tact is required!
If you want to include racist, religious or sexist prejudices in your game, you have to do it responsibly. Think about how you enrich the game with it and be mindful of others. We are available for discussions in advance. Out of game we are committed to equality and against racism. Everyone can play what they want to play, regardless of skin colour or gender; however we reserve the right to reject concepts that we deem insensitive.

Alcohol and drugs. It can happen that you shouldn't have had that last drink. At that moment, you definitely do not belong in the active event. Illegal drugs have no place at our event whatsoever.
