Check out the site for the TRG trainer, RCT2 can have "Plugin scenery" it looks kinda fake, but I think it will work. I tried it, but I couldn't get it to work. The TRG Trainer is awesome, I use the no sound button so I can listen to music, and now they added a "Mountain Building Tool". Anyway this may mean we could put Disney related stuff into the game! We'll see...
