    When the Internet powerhouse Yahoo wanted to teach ethics(道德标准) to its employees, it
faced a challenge familiar to multinational companies.
    Yahoo employs nearly 14,000 people at 25 sites worldwide. They would feel bored at sitting
down in front of a dated video in which actors with 1980s haircuts tell them what to do. So it hired
a company calledThe Network <http://www.ks5u.com/> to design a game. In the game, the truck
where Yahoo was founded traveled the world, turning into a boat and a helicopter along the way as
it visited some of Yahoo's foreign offices. Participants play in game show-like scenarios(场景) that
quiz them about conflicts of interest and doing business fairly. And employees note: Yahoo is tracking
how well they do.
    Such activities draw more enthusiastic participation and teach more effectively than traditional
methods. They are described as alternative-reality games (ARGs), involving both interactive and
real-world elements. Besides teaching employees, ARGs have also been used in many areas for a
number of different purposes.
    From a marketing perspective, a number of very successful ARGs have been written as a way to
build product awareness. A very popular ARG called I Love Bees was produced to market the
2004 video game Halo 2 <http://www.ks5u.com/>. At its height, I Love Bees received between
two to three million unique visitors over the course of three months.
    ARGs are more than just a fun way to learn. They have also been used to solve real world
problems. An ARG called World Without Oil <http://www.ks5u.com/> was created to obtain
collective input from players about dealing with the world's dependency on oil. World without Oil
simulates(模拟) the first 32 days of a global oil crisis and anybody could play by creating a personal
story that recorded the imagined reality of their life in the crisis. World Without Oil's success on a
small budget has opened the door for similar games to engage mainstream Internet users with climate
change, education reform, governmental policy and other timely, vital issues.
