Simultaneous Action Selection

Crossing

In Crossing, you have to collect gemstones, but players make their choices simultaneously and not everybody will get what they want when desires clash — and even if you are lucky during the initial confrontation, you aren't safe from the greediness of other players.

Through bluffing and cunning, you want to collect more gemstones than your opponents. To do this, you place a set of cards side by side on the table, with each card featuring a varying number of gems. When signaled, each player simultaneously places a finger on one of the cards. You collect the stones only if you are alone on the card!

The French version of Crossing includes rules for play with only three whereas the initial Japanese release of Xing included rules only for 4-6 players.

Histrio

It's that special time of year when the entire kingdom gathers at court for the Munificent Theatrical Festival. Acting troupes from all over the land will come together to perform plays of light-hearted comedy or soul-wrenching tragedy. Will their performance win the favour of the king or will his fickle mood spell a flop?

In Histrio, you travel the land recruiting actors to join your troupe. Assemble the right team and you might earn enough money to pay for an entire year of shows. It'll take careful planning and a little luck to out-perform your competitors. The play is the thing in Histrio, and the world is your stage!

Grimoire

Grimoire is the French word for "spellbook", and smart use of your spellbook – more specifically, the spells within said book – will determine whether you succeed in this game.

Each turn in Grimoire starts by revealing several cards on the game board; each card has either a victory point (VP) value or is a character with a particular way to earn VPs at the end of the game. Once these cards are revealed, each player secretly chooses which spell to cast in his spellbook by placing a bookmark on the appropriate page. Everyone then reveals which spell they chose, with the spells going off in order from weakest (those with the lowest numbers) to strongest. Some weak spells nerf stronger ones, and the order in which players choose cards from the display can be flipped topsy-turvy depending on who plays which spells.

In the One Draw and Z-Man versions, the game ends as soon as one player has collected either ten character cards or ten treasure cards; in the Schmidt Spiele version, the game ends after a fixed number of rounds. All players then tally their points, and the player with the highest score wins.

Differences between the versions:

As noted above, the game ending conditions differ in the 2012 Schmidt Spiele version.
The Z-Man Games and Schmidt Spiele versions of Grimoire accommodate five players, while the original One Draw release allows only 2-4 players.
The Schmidt Spiele version contains four new character cards and two new treasure cards, includes hardcover books instead of softcover, changes two spells, and uses a more elaborate game board that depicts the spells and allows players to mark the spells chosen with small figures to track who has played what.

Karuba

This is a tile-laying race game with players starting with boards that are identical, and one player drawing tiles that they all will use. They race to get their explorers to temples first and earn points. Along the way they can collect additional points by collecting items off the paths they create.

Description from the English Ruleset:

Many moons have come and gone since your boats departed on the journey to Karuba. Once you arrive on the island, each player will lead an expedition team of four adventurers. Now you just have to navigate your way through the dense jungle to make it to the temples. „Just“ may be something of an understatement; the ancient jungle trails have to be found and uncovered first! Hurry up and be the first to reach the temples to collect the most valuable treasures. Many paths have dead ends and you need to be patient to find the right/best way (through the jungle). Look! A gold nugget! You can pick it up and collect it, same applies to the shiny crystals along the paths.

Mombasa

In Mombasa, players acquire shares of chartered companies based in Mombasa, Cape Town, Saint-Louis, and Cairo and propagate trading posts of these companies throughout the African continent in order to earn the most money.

Mombasa features a unique, rotating-display hand-mechanism that drives game play. Each round players choose action cards from their hand, then reveal them simultaneously and carry out the actions. These cards are then placed in a discard pile, and the previously played cards recovered for the subsequent round.

Each company has a double-sided company track, so games will vary quite a lot based on which tracks are revealed and at which companies they are placed.
