Megaworld Park/Scenario Guide

First, '''PAUSE THE GAME. Hire a large number of handymen and assign them where necessary.' (This can be done with pause on, which might prove very useful, and Open RCT2's auto-placement feature makes it even faster.)''

Keep adding stalls until you have each about 20 bathrooms, food/sweet stands, and drink stalls, in addition to a few Information Kiosks and Souvenir Stalls to provide umbrellas when it rains. Place some benches and bins near the exits of the park's roller coasters, as most of them are very intense and nauseating. Use "No Entry" signs to block off ride exits to prevent guests from getting lost or wandering into dead-end paths.

After you have covered the basics, some of the rides need fixing. Shorten any ride that takes over 3 minutes and shorten the queue lines, or alternatively, add a second station. The Go Karts should be set to "Continuous Circuit Mode" to reduce the duration. Check the settings of your rides, as some have very long waiting times between the cars, which causes unnecessary queues.

The Steel Corkscrew Roller Coaster, Viper, in the desert area to the right of the entrance also has too high an intensity rating, which has to be fixed by flattening the track a bit, banking whatever can be banked, and removing an inversion or two. Be sure to add a brake line near the end to reduce the chance of Station Brake Failure crashes. The excitement rating can rise to about 8 even with minor edits.

You should also edit the Inverted Roller Coaster, Purple Peril, by removing some inversions, decreasing the nausea rating significantly even though it will remain relatively high. Consider demolishing and replacing both of them as another option. The Steel Mini Roller Coaster, Spinner, will be far less nauseating if you replace spinning cars by non-spinning ones, although the name would be rendered meaningless. You can also remove this ride and replace it by another one you might research.

While you are busy repairing, the park rating will recover steadily and finally, guests will start streaming in your park. You will not need many more rides, but still, squeeze in what you research.

Good options would include replacing the Viper Coaster by a smoother design, like a Steel Twister Roller Coaster. Another idea is to delete the Steel Mini Roller Coaster in the mountains on the far-right corner, and use the station of this ride to place an Air-Powered Vertical Coaster.

A third idea is to replace the "Thunder Mountain" Mine TRain ride in the same sector, and replace it with any newer coaster of your creation.

If you play it on RCT2
Several good options to this scenario if you play it on RCT2 :
 * Replace the Viper Coaster by a smoother design, like a Hyper Coaster,  a Giga Coaster, or a Steel Twister Roller Coaster. If you keep the replacement coaster short enough, you can squeeze a Vertical Coaster towards the Batty Bikers ride and as such multiply the thrills.
 * Remove at least two inversions on the Purple Peril rollercoaster. The ride's intensity must go below 9. Consider removing the whole coaster and building a new one instead if you prefer.
 * Expand the stations of the Monorail Shuttle on the bottom-left corner of the map, to increase it's capacity.
 * On the same ride, try to remove any unnecessary incline and curve, and try to keep the ride as flat as possible, in order to increase the trains speed, and therefore, the ride's efficiency through guest capacity.
 * Bank the curves of the Wooden and Steel Looping Roller Coasters wherever applicable, to decrease their intensity ratings.
 * If you feel like building a Giga, Hyper or Hyper-Twister coaster, don't try to create ultra-tall heights : you'll waste more time than needed. A couple 40m falls above ground and a few knots below, are more than enough for the same profits.
 * Consider demolishing one of the two wooden coasters, to replace it by a ride you might research. I'd suggest you to demolish the Cyclone, which is prone to station brakes failure. However, avoid the Side-Friction Coaster, which is unable to have steep hills.
 * If you try to create a Wooden Wild Mine Ride in the Mine Sector, remember to keep it short and with a short queue, as this ride has a very small guest capacity and will lead to insanely long waiting times if it's too long.
