Clock-based video games

Clock-based video games tie all unit actions directly to the game clock. Turns begin and end depending on the duration specified for each action, resulting in a sequence of turns that is highly variable and has no set order. This system is frequently cited for its realism when compared to other turn-based systems. It is also possible in this system for different players' actions to occur at the same time with respect to the game clock, as in real-time or simultaneously-executed games. Examples of video games that use this type of system include Typhoon of Steel (1988) and MechForce (1991), both originally developed for the Amiga.
