There are a total of 21 scenarios, with an additional scenario available on the official site of RollerCoaster Tycoon. One complaint I have with the game is the lack of a blank slate in which the user creates an amusement park completely from scratch. I would enjoy using my creative energy to completely design a creation completely from the ground up. Since the scenarios continue after the objectives are met, the gamer can bulldoze and rearrange the park to their heart's content. Not all scenarios are immediately available.
Additional scenarios become available as the gamer conquers the previous scenarios.
Each scenario can be saved at any point in the game. This is a necessary feature considering the length and complexity of some of the scenarios. The difficulty of RollerCoaster Tycoon is a nice mix of incredibly easy games up to fairly challenging. Preplanning is definitely a must in the situations in which very little land is available. Each scenario begins by offering the user a limited number of different items to choose from.
