Park Files

This is the incomplete shyguy's Main Street, including the image pack for use with shyguy's billboard shelves in the Main Street Set 4.

This is Water World, Mr. Wonder's second major park.

This is Circus Center by itself, for those with slower computers.

This is Expo 3000 by itself, for those with slower computers. It includes the new Transport Center.

The east side of Wonder World, which includes Expo 3000 and Circus Center. You'll need the Expo 3000 and Circus Center cs sets. (possibly others)

The west side of Wonder World, which includes Alpine Village and Catfish Cove. You'll need the Alpine Village and Catfish Cove cs sets. (possibly others)

This is the first phase of Wonder World, before any custom scenery was used.

Based off this page from the Theme Park Fanon wiki, this is Six Flags Indiana as it appears in 2018, the year before SF randomly drops the ball on what is essentially an elite park for no reason at all. New for 2018 is Total Mayhem, an S&S Free Spin located near Apocalypse.
 
You're going to need the following CS and CTRs:
Six Flags Entrance (IDK who made it sadly)
Nightflight CTR (again, no clue who made it)
JCat's Steelworx
Moby's Steel Jungle
Sanba Balloon
Red Baron
SpaceShot and TurboDrop (maybe by ImagineerJohn? I forget who made them)
That one waterpark CS set that has the tipping bucket (forgot the name)
ATH Catwalks
SafariJ's Arrow Supports
 
And you need Soaked and Wild to open the park. If you have all those, enjoy!
