Setup your website, hook up to search engines and place banner ads on other players' sites. Why? To attract subscribers. Because the more subscribers you have, the more your site is worth and the more lucrative when you float on the stock market. Here, timing is all; too soon  and you'll not have enough subscribers; too late and the market may have collapsed. And then there are other players manipulating the market against you.
Play finishes when the stock market reaches zero or all players have cashed in. The wealthiest, wins.
An interesting game that introduces the world of dot.com business in a light and easy way.
