Description
Actions are rated for speed or initiative. Faster actions are executed first.
Discussion
This system is most commonly used in Simultaneous Action systems (TRN09). In Critical Mass, each player selects an action card from their hand and plays it simultaneously. Each is rated for speed, and faster actions go sooner than slower ones. Critical Mass uses numeric speed ratings. Some games use descriptors, which can be as simple as Fast or Slow, as in The Ares Project, or more thematic, like First Strike in Magic: The Gathering. While this often represents the speed of an action, it can also be more abstract. In Libertalia, characters have a priority rating and operate in the order of priority from lowest number to highest. Typically, if actions have the same speed, they are resolved simultaneously, although a tiebreaker may be used (RES-18). Each card in Libertalia, for example, has a unique number on it as a secondary tiebreaker. Speed ratings give players a clear indication of the order of execution of actions, and the designer another resource to use for balance purposes. Faster
actions can be weaker, while slower actions can be more powerful, but more likely to not take effect.

描述
行动按速度或主动性评级。较快的行动先执行。
讨论
该系统最常用于同时行动系统（TRN-09）。在《Critical Mass》中，每位玩家从手牌中选择一张行动卡并同时打出。每张卡都有速度等级，较快的行动比较慢的行动先进行。《Critical Mass》使用数字速度等级。有些游戏使用描述符，这可以像《The Ares Project》中的“快”或“慢”一样简单，或者更具主题性，比如《万智牌》（Magic: The Gathering）中的“先攻”。虽然这通常代表行动的速度，但它也可以更抽象。在《Libertalia》中，角色有优先级评级，并按优先级从最低数字到最高数字的顺序操作。通常，如果行动具有相同的速度，它们会同时解决，尽管可以使用决胜局（RES-18）。例如，《Libertalia》中的每张卡都有一个唯一的数字作为次要决胜局。速度评级为玩家提供了行动执行顺序的明确指示，并为设计师提供了用于平衡目的的另一种资源。更快的
行动可能较弱，而较慢的行动可能更强大，但更可能无法生效。
