Greentube, the worldwide leading provider of free 3D download games and turn-key gaming platforms, has launched the fourth season of its global hit “Ski Challenge” with a range of new features including optimisation for Windows Vista and a new track.

Ski Challenge 08 has been licensed to various different media-partners, primarily TV-stations and leading newspapers in 7 different countries so far – including Norway, Germany, Switzerland, Austria, Slovenia, Croatia and Canada.

After more than 3 million players last year, Greentube is expecting between 4 million and 5 million players worldwide between now and March 2008. This figure seems to be quite a conservative estimate, as within only 2 weeks after launch, the different editions of Ski Challenge have been downloaded more than a million times!

Greentube has been working hard on updating the game with latest 2.0-features such as a video creation-tool directly embedded within the game.

The free download game is fully financed via in-game advertising and includes advertising brands such as Siemens, Audi, Telenor, Swisscom, Visa, Samsung, Red Bull, to name just a few. Most of the advertising brands have been partners of this game since the beginning in 2004, as the advertising value and image-transfer effects generated by the game are more than convincing.
