I absoutely love RCT 3. I love the roller coasters, I love the fact You can actually ride your very own rides, I love everything about it. It may be older, but its the best! And I wanna learn more on how to do more things. Thats why I'm asking, how in the heck do You find the all of the objects for things (For example, Disneyland's rides) thats not even in the game itself? Can I get some guidance here? Thanks guys. Its highly appreciated.

Its on CS websites. Try vodhin.org. Theres alot of CS there.

But currently, Vodhin is members-only, and you would have to know how to install CS.

CS is also very easy to install. Just place the CS folder in the Style/Themed folder.
