未磨练的

Boys will often play the games, struggling to master a challenging level, well past the point of physical and emotional exhaustion. Children are not so much "addicted" to video games as they are unwilling to quit before they have met their goals, and the games seem to always set new goalposts, inviting us to best "just one more level." One of the limitations of the contemporary video game is that it provides only pre-structured forms of interactivity, and in that sense, video games are more like playgrounds and city parks rather than wild-spaces.

内容大概是不断的尝试跟失败与遵守规则，是让给玩家的一种磨练，在游戏里面不断的练习来达到能力提升完成目标，现在多数的电脑游戏都是属於冷酷无情与目标导向的游戏，男孩子会时常玩这类的游戏，勇於尝试具有挑战性一关接一关，一直到无法无天体力与情绪耗尽为止，小孩子并不是对於游戏沉迷上瘾，而是未达到目标之前不愿意离开游戏，游戏里面总是有很多新的挑战，让我们一直不断的接受下一关的诱惑或是有更好的自我表现。
