Simultaneous Action Selection

Diplomacy

This classic game of pure negotiation has taken many forms over the years.

The first Avalon Hill version has perhaps the widest release, but Avalon Hill (Hasbro) re-released the game in 1999, complete with a colorful new map and metal pieces. They recently released a 50th anniversary edition with a new map and cardboard pieces representing the armies and navies.

In the game, players represent one of the seven "Great Powers of Europe" (Great Britain, France, Austria, Germany, Italy, Russia or Turkey) in the years prior to World War I. Play begins in the Spring of 1901, and players make both Spring and Autumn moves each year. There are only two kinds of military units: armies and fleets. On any given turn, each of your military units has limited options: they can move into an adjoining territory, support an allied unit in an attack on an adjoining territory, support an allied unit in defending an adjoining territory, or hold their position. Players instruct each of their units by writing a set of "orders." The outcome of each turn is determined by the rules of the game. There are no dice rolls or other elements of chance. With its incredibly simplistic movement mechanics fused to a significant negotiation element, this system is highly respected by many a gamer.

City of Horror

City of Horror is a backstabbing survival-horror game. As in classic zombie movies, a shambling horde is invading the city. The goal is to survive the assault. (Un)fortunately, surviving often means sacrificing some of your fellow players to the undead...

Each player controls several characters with different abilities; these characters can move to various limited-capacity locations, which they can then barricade and scavenge for items and weapons. Critical situations, such as zombies breaking in and eating a character, are resolved using vote.

The basic game mechanisms are the same as in Mall of Horror (also designed by Nicolas Normandon), but City of Horror differs in both materials and game play in a number of ways: the city map changes each game, twenty characters are included, they can use antidotes (or die), action cards become scarce as the game goes on, you can gain points with other stuff than surviving characters...

Basari

Several games use the simultaneous action selection mechanism, but this is perhaps one of the best.

Basari is a game of gem merchants competing in a marketplace, racing, collecting, trading, and predicting what the other merchants will do.

To start the game, players receive 12 gemstones (3 each of 4 colors).
Each turn there will be a movement phase and an action phase:

For movement, everyone simultaneously rolls their die and moves their markers around a track.

They then choose one of three different actions to perform. The actions are:
- to take a variety of gems from a market stall,
- to immediately score from between 4 and 7 points, or
- to roll and move again and also collect points.

The action cards are revealed simultaneously. If only 1 player chose a particular action, they simply perform that action. If 2 players chose the same action, they barter back and forth with gemstones. One player will eventually accept the other's offer of gems, and the other will take the action. If 3 or 4 players all chose the same action card, that action is cancelled. Note that in 4-player games, there will always be a conflict in choice of 3 actions, so much more negotiating goes on.

A new turn begins with everyone rolling their die, moving, then choosing and revealing their action cards. When any merchant piece completes a lap around the board, the round ends and bonus points are awarded based on who has the majority in each gem color and who has completed a lap. After three rounds, the game is over and the highest score wins.

Amberden Affair

Conspiracy is served...

In The Amberden Affair, players serve as domestic servants for a grand soiree held in the esteemed Amberden Manor. While busily carrying out orders for three distinguished dignitaries, observant footmen realize that one of their own has malicious objectives that threaten the very lives of the ones they are there to serve.

In the game, players try to earn points by completing as many orders as possible by taking item cards from locations in the room and bringing them to their proper recipients. They must also attempt to identify the Miscreant Impostor, the player who is secretly trying to poison certain targets while accomplishing regular orders. The player with the most points at the end of three rounds wins!
