This is a park that will consist mostly of Roller Coasters. At the beginning of the scenario, no gentle rides are available, and you are limited with your thrill rides. During the course of the scenario, you'll develop a few, but the game researches mostly new Roller Coasters and Themes. Here, most guests intensity rating is "more than 9", so gentle coasters won't work out. Good coasters to attract guests to the park are coasters with high excitement ratings, but keep both intensity and excitement ratings high enough, or no one will ride.
