Wargaming meta-turn sequences

In information technology speak, “meta” means one level of description up. One thing I’ve been meaning to do is start cataloging various game design metaconcepts. I’ve decided to start with turn sequences. Listed below are the turn sequences that I can think of. If you know of any more, please comment so they can be added to the list.

The word “activation” is used throughout this explanation and in this context means performing the game activities and subsequent effects for one game unit. This can also be called “unit activation”

Alternating Player Turn (aka IGOUGO). A turn sequence in which one player performs all the activations for their side and then the opposing player does the same. Activity then alternates back to the first player, and so on, until the game is finished.

Alternating Unit Activation. A turn sequence in which one player performs an activation for a unit of their choice and then the opposing player does the same. Players alternate activating units until all units have had a chance to activate at which point a turn is complete and the cycle starts again. Games often have a mechanic to determine who activates first.

Assigned Random Unit Activation. A turn sequence in which a unit belonging to either player is randomly chosen (often by assigning the unit to a card and then drawing cards) and the controlling player activates that unit.

Unassigned Random Unit Activation. A turn sequence in which one side is randomly chosen and the player activates a unit of their choice. This system often keeps the probability of one side being chosen in direct proportion to number of units both sides have in the game. This is often accomplished by using one card per unit in the game and then allowing the side that had their card drawn select a unit.

Nominated Random Unit Activation. A turn sequence in which both sides declare a unit and randomly determine which side is allowed to activate their selected unit (typically by dice roll or by some sort of bidding process). The losing player may then be allowed to activate their unit or both players may declare another pair of units and repeat the process.

Simultaneous Activation. A turn sequence in which both sides simultaneously perform the game activities for the units on their side which is often accomplished through the use of secret and written orders for the units. This mechanic is often used in Naval and Aircraft games (and their Science Fiction equivalents).
