With the action/movement programming mechanic, each player chooses their actions for several turns and then players execute their actions according to the choices they made. Some games require the players to choose these actions secretly (RoboRally), while others allow players to work together and show their teammates what they intend to do (Space Alert). Usually, several actions are at the player’s disposal at any one time and if the player misplays their actions, the result can be a humorously monumental mistake. Most action/movement programming games have events during the course of a turn that can change the status of the playing field in ways a player did not anticipate or in manner they hoped didn’t occur before their action was executed.
