Is there any way to disable the RollerCoaster Tycoon 3 expansion pack content and just play the vanilla game?

The new Soaked and Wild stuff seems to be mixed in with the "normal" RTC3 Career mode, and I can't find any way around that.

Thanks!

I haven't 100% tested this, but might be worth a try.

Go to your RCT3 directory.
(C:/GOG Games/Rollercoaster Tycoon 3 Platinum/)
Then go into the folder ContentPacks/

Remove the contents of the ContentPacks folder, and place them somewhere else as backup.
(for example make a RCT3 Backup Folder on your desktop and place them in there.
I have 4 files in there named something like ContentPack0000)
The ContentPacks folder should now be empty.

Like I said I haven't fully tested it but what I've noticed when running the game is in the Campaigns menu
the Soaked and Wild are greyed out.
You'd have to test whether the content still shows up in the Main Campaign or not. Though I have a feeling it won't.
