And so, sort of, the crux of this presentation is going to go through four really important game dynamics, really interesting things, that, if you use consciously, you can use to influence behavior, both for good, for bad, for in-between.
所以我今天演讲的关键就是 四种重要的玩游戏的动机，非常有趣， 如果你意识到， 你就可以用这些动机来影响人们的行为， 既可以朝着好的方面施加影响，也可以带来坏的影响，或者让它们同时发生。
