The target audiences of the cartoon TV series, Lost Dinosaur Valley are boys around 12. For this project, a 22-minutes-per-episode, 24-episode TV drama together with a 85-minute movie are now in progress. The story tells about two antagonistic dinosaur tribes, in order to save themselves from the intruding alien army, form a battle alliance and finally defeat the high-tech extraterrestrial civilization. The clear story line with lots of affecting climaxes makes it could be adapted into RPG games. In the story there are also many quests to be accomplished by the characters, thus it’s also fit to be adapted into on-line games. The originally designed cartoon characters, especially the avant-garde alien images are suitable for the development of related products and franchising.
