Simultaneous Action Selection

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!

Gravwell: Escape from the 9th Dimension

In Gravwell: Escape from the 9th Dimension, players command spaceships that have been pulled through a black hole, transporting them into a different dimension. With each ship lacking fuel to get home, each player must collect basic elements from surrounding asteroids, using the gravity of the dimension and what little resources they have in order to reach the warp gate that will take them home. But in this dimension, moving ships will travel towards the nearest object, which is usually another ship, and when those objects are moving either forward or backward, reaching the warp gate isn't always easy. Time is running out to save your crew and your ship! As a grim reminder of the cost of failing to escape, the frozen hulks of dead spacecraft litter the escape route – but with careful cardplay, you can slingshot past these derelict craft and be the first to escape from the Gravwell!

This easy-to-learn game uses 26 alphabetized cards to determine movement order and thrust; most cards move your ship towards the nearest object, but a few move you away from it. Players will draft fuel cards in each round – picking up three pairs of two cards, with only the top card of each pile being visible – giving you some information as to which moves you can expect from the other spaceships. During a round, each player will play all of his fuel cards in the order of his choosing. During each phase of a round, each player will choose one card, then all cards are revealed and resolved in alphabetical order. When your opponents move in ways you didn't expect, you won't always be heading in the direction you thought you would! Each player holds an "Emergency Stop" card that he may tactically play only once per round to avoid such a situation.

Whoever first reaches the warp gate wins, but if no one has escaped after six rounds, then the player who is closest to the gate wins.
