Time-keeping systems in games

In video and other games, the passage of time must be handled in a way that players find fair and easy to understand. This is usually done in one of two ways:

In real-time games, game time progresses continuously according to the game clock. One example of such a game is the sandbox game Minecraft, where one day-night cycle is equal to 18 minutes in real time. Players perform actions simultaneously as opposed to in sequential units or turns. Players must perform actions with the consideration that their opponents are actively working against them in real time, and may act at any moment. This introduces time management considerations and additional challenges (such as physical coordination in the case of video games).
