Mega Park

Overview
This park is the reward for completing every original RollerCoaster Tycoon scenario. The park features theming from many other scenarios in the game. There is no objective the this park, but it uses money, which means it is not a true sandbox mode. However it's definitely worth unlocking.

Scenario Guide
Since there is no proper objective, you will not need a guide. Mega Park can almost be thought of as a sandbox; the only thing stopping it from being an actual sandbox is that you still start out with $10,000, due to the fact that scenarios could not have unlimited money in the original RollerCoaster Tycoon.
